And so it goes: Suicide Squad is finally here after being dragged through the dirt by critics prior to release, and you know what? It's not all that bad.

Like the other movies in the DC Extended Universe, Suicide Squad doesn't seem all that sure about what it wants to be, and what it wants its characters to be. But, like the other pieces in the shared universe, it's also packed full of connections to its sister movies and those yet to be birthed.

We've known for a while now that Justice League founder Batman (Ben Affleck) was set to make an appearance in Suicide Squad, propping up the Joker (Jared Leto) and Harley Quinn (Margot Robbie)'s backstory. He did more than that, as it turned out, but he was also joined by a surprising cameo that we weren't expecting, and it reveals a few interesting things about a certain Justice League member.

Quick As A Flash

Reportedly filmed during the post-Batman v Superman: Dawn of Justice reshoots was the unexpected Flash cameo from Ezra Miller's Barry Allen. We first met Flash during Batman v Superman, as Barry travels back in time through use of what appeared to be a Speed Cannon to implore Bruce to save Lois Lane (Amy Adams).

He appeared again later in the movie as part of Lex Luthor's (Jesse Eisenberg) metahuman files, where Wonder Woman (Gal Gadot) watches security footage of him foiling a convenience store robbery.

During this scene we see several other files under his profile labelled "Redstreak", suggesting that around the time of Batman v Superman he's already been flashing around in his trademark red suit.

We got a better look at the suit in the Justice League trailer, and we see it again in Suicide Squad, when Flash apprehends Captain Boomerang/Digger Harkness (Jai Courtney). This suggests that, by the time he's recruited into Batman's Justice League, Barry Allen will have been the Flash for a decent amount of time, long enough to have made a name for himself along the way.

In Amanda Waller's (Viola Davis) dossier we learn that Harkness has come to America after robbing every bank in Australia. Clearly he picked the wrong bank to rob though, as he's apprehended by Flash after double crossing his accomplice. Is this bank in Central City? It seems likely.

The scene was actually directed by Zack Snyder as part of the Justice League set, meaning that the suit Miller sports in this cameo is the same as we'll be seeing in Justice League. As Ayer told Cinema Blend:

"Flash had always been in the script, but I got lucky, because of -- I don't want to speak out of school or anything like that, but I got lucky because [Justice League] is going, and they had Ezra and they had the costume, and it's like, dude, give me, give me, give me."

Feeling Blue

In the Suicide Squad cameo we get another look at the Flash's lightning, which fans of the DC TV show will have probably noticed is blue, not red. The Flash of the comic books is typically portrayed with red or orange lightning generated by his speed. The Speedforce is also portrayed as red and orange, whilst the Flashpoint event was portrayed with blue lightning in DC Universe: Rebirth.

In the comics blue lighting is also linked to Cobalt Blue/Malcolm Thawne, Barry Allen's New Earth twin brother, and Future Flash, an older and darker version of Barry Allen from the future.

Whilst the red lightning is an aesthetic choice to match the Flash's costume, it can also be used to reflect certain aspects of the character — something which is often addressed in The Flash TV show. The evil speedster Hunter Zolomon/Zoom (Teddy Sears) generates blue lightning when he runs, a visual which is later linked to the effects of the dangerous speed-drug Velocity 9. V9 also causes Barry Allen's (Grant Gustin) lightning to turn blue when he uses it, and eventually kills the blue lightning sporting speedster Eliza Harmon/Velocity (Allison Paige).

There's a few reasons for this stylistic choice here, likely another way DC hope to distinguish the Flash of the DCEU from the Flash of the TV show. It's speculated that the blue lightning in The Flash is linked to the speed at which a speedster can travel, so does this mean that the DCEU Flash will be even faster than the DC TV show version, or is he using performance enhancing drugs?

Will Boomerang Return?

Though Captain Boomerang has long been the spineless class clown of the Suicide Squad, he was first known as a classic Flash antagonist harking all the way back to the 1960s. Having Flash being the one to catch the Aussie criminal was a nice touch, and it could be setting him up for a return in The Flash solo movie. It's worth noting that we've already had a DC TV version of Captain Boomerang too, in the Flash vs Arrow crossover.

Given his status as a Flash-botherer, and also given how little we know about the solo movie, it wouldn't be a big surprise to see Captain Boomerang returning outside of the confines of a potential Suicide Squad sequel. Introducing characters in ensemble pieces to later be built upon is very common in shared universe franchises, so perhaps we'll see the beer chugging Aussie returning again like his namesake.

One thing is for sure though. As she manipulates Boomerang, Waller has also been aware of the existence of the Flash for a while by the time the events of Suicide Squad roll around, months after the events of Batman v Superman. So the metahuman is certainly on her radar, though we never see if she's attempted to reach out and contact him.

Waller's Gonna Get'Cha

In the mid-credits scene — which I have dubbed Waller v Wayne: Dawn of Dick Measuring — we briefly see Barry Allen again, albeit in photographic form. This time he's joined by the always majestic Jason Mamoa (Arthur Curry/Aquaman) as part of Amanda Waller's meta-human dossier, setting up Justice League nicely.

This scene does a few things. Perhaps most interestingly it establishes an uneasy working relationship between Waller and Wayne, reinforced by the fact that the company who produced the infamous neck bombs Waller uses to keep the squad in line was Van Criss, a subsidiary of WayneTech.

We also learn Bruce isn't too happy about the Suicide Squad, demanding Waller shuts the program down. He and "his friends" will take care of the bad guys from here on out, he promises. Waller counters with the stone cold line about Bruce needing to stop working nights, revealing that she knows the real identity of the Caped Crusader and won't hesitate to use it against him.

They leave at a stalemate, and Bruce now has the knowledge he needs to begin building the Justice League. But now that Waller has a hand in it, what does this mean for the team? You think someone as cold, ruthless and calculating as Amanda Waller would pass up an opportunity to gain leverage over the most powerful metahuman team in the world? Watch this space closely, we have a feeling we haven't seen the last of Amanda Waller and Bruce Wayne.
