Since the official release of the Comic-Con Suicide Squad trailer, there have been many theories floating around regarding whom the Joker is torturing in the trailer. My first thought, along with many others', was that the Joker is speaking to Jason Todd as he delivers his bone chilling line: "Oh I'm not gonna kill yah. I'm just gonna hurt yah. Really...really, bad!" This would make sense as Joker did in fact torture Jason rather than kill him. At least at that particular moment. Later Joker leaves Robin/Todd to die in the warehouse as a bomb detonates before Batman can reach the Boy Wonder. However, after doing a bit of online research and some heavy reviewing of the trailer, I am 99.999% positive that the Joker is not torturing Todd, but rather Dr. Harleen Quinzel before she took on the persona of Harley Quinn; before losing a bit of her mind.
"But why would the Joker be torturing his Harley??! That's a ridiculous assumption!!"
Well yes, it may seem a little absurd, but let me remind you the The Joker and Harley's relationship has been a consistently abusive one. Physically and mentally. But still, that's not really enough evidence to support the theory that Mr. J is laying down the pain on Harley. I was reluctant to believe at first but as I said, I've done a lot of reviewing. Lots of really quick pauses on YouTube. The following is my supporting evidence:
My theory for this photo and the following is that these masked goons with guns are actually breaking Joker out of Arkham Asylum. Maybe not so much in this scene as it looks like some sort of factory, but perhaps these goons are recurring? This will make more sense later. The panda is significantly important so keep that in mind.
The above photo looks a lot more like the Arkham we all know! Still though, goons with guns!
This photo is important. Notice to the left our masked panda is ever present as the goon hidden to the right apprehends Harleen Quinzel in her smock. Notice that lamp above that table? It's important.
Again with the lamp... Also, Harleen's glasses are really important. You'll see why in a bit.
Woah! There's our panda friend again and that lamp shade hanging right above the table Harleen was thrown on to. This confirms that Joker is indeed approaching Dr. Quinzel. The panda was previously seen in the same room as Harley as she is apprehended. It's all starting to come together...
This is the original shot that got everyone thinking that the Joker was indeed torturing Harley rather than Jason. Some however, refused to believe this. Observe however, with the former photos in mind, that Harleen is still wearing her smock seen earlier and glasses. Also, that lamp is shining a lot of light down on Dr. Quinzel there. Coincidence? Nope!
Now here's the real confirmation. All of the photos have chronologically led up to this point. The Joker approaches the table with the lamp shirtless, he's still shirtless here. This is the same room where we saw our panda buddy and where we saw Dr. Quinzel forced on to the table. And that lamp shade still hangs overhead. But the real spoiler is the GLASSES! Look very closely at the lower right hand corner of the photo. You can't really see her head as it is hidden by the table in the foreground but look at the glasses. Those same thick-rimmed black glasses that Dr. Quinzel was wearing? Well...she's still wearing them. That is indeed Dr. Harleen Quinzel.
Joker is still clearly holding the same electrodes as in the previous photo with the intent of hurting Harleen "Really...really, bad."
Doesn't Leto's smile just give you the chills??!
I'm not sure what to think with this photo. This is the same factory looking environment that the goons were shooting up. My theory is that Joker is either entering this facility with the same goons that helped him escape Arkham, or that this is some part of the Asylum. Who knows?
That concludes all of my photographic evidence to support my claim. I'm not sure what all of this means and how it will play into the Suicide Squad story but I am sure that Dr. Quinzel is going to be tortured by the Joker. My assumption is that this is going to be a part of Harley Quinn's origin story. Who knows what Joker could have told Dr. Quinzel? What kind of ideas could he have made her to believe. Torture has been used as a device to obtain information. Couldn't it be a pretty good convincer in making someone believe something or another? Either way, the whole experience is most certainly going to by psychologically traumatic to Dr. Quinzel which will certainly lead her into madness. Thus Harley Quinn will be born. Piece it together yourself in the trailer below and see what you think.
