What began as a simple show about a masked vigilante has turned into an entire universe of characters and parallel worlds. From Star City to Central City to National City and all of time and space, the shared universe known as the “Arrowverse” has become a hit phenomenon for the CW and DC Comics.

During the course of the last five years, there have been several character deaths and events that have changed the status quo and driven the storyline forward. Some left more questions than answers. For example, where did Eddie Thawne’s body go after being dragged into the black hole? Plot holes like this and others leave fans guessing and speculating about possible signs that bigger events are coming.

With any luck, the four loose ends below will be tied up in the new season of Arrow, The Flash, Supergirl, and DC’s Legends of Tomorrow. If they are not, the flames of speculation and conspiracy will only grow surrounding these characters and their circumstances.

4. Is Eddie Thawne Really Dead?

If Eobard is still around, what did I do this for?

Poor Eddie Thawne. First he had to compete with a CSI geek for the heart of his own fiancé, then he had to sacrifice himself to save both his fiancé and his rival for her affections.

When all hope seemed lost and Eobard was about to kill Team Flash, Eddie made the ultimate sacrifice and killed himself in order to erase Eobard from existence. Because Eddie died without having children, Eobard was never born and he was wiped from reality (at least until he made appearances in Season 2, 3, and Legends of Tomorrow).

Following his death, Eddie’s body was sucked into the black hole that formed over Central City and he has not been seen since. Now that we know the black hole was likely a portal to Earth-2 (or any other parallel world), it is possible that his body was sent to an alternate reality. It is also possible that his body landed on a world that could bring him back to life. If so, it is very likely that we will see him again in the future. Not only could he come back from the dead, but his new lease on life could be the reason Eobard is able to continue being a menace in the Arrowverse.

3. Is Ronnie Raymond Really Dead?

Earth-2 or bust!
Earth-2 or bust!

Following Eddie’s example of self-sacrifice, Ronnie detonated himself inside the black hole in order to save Central City and the world. Like Eddie, his body appears to have gone into the singularity before it collapsed.

In comics and TV, if there is no body to bury, it is very likely that the character will return to life at some point. While Ronnie’s “death” paved the way for the new Firestorm to emerge, it is possible that Robbie Amell’s character could return to Central City as a hero or a villain.

Fans have already been introduced to a villainous version of his character on Earth-2, when his doppelgänger Deathstorm teamed up with Zoom during Season 2. Could a near-death experience turn Ronnie to the dark side and allow him to re-emerge as the Earth-1 version of Deathstorm? Could he find his way to his home planet and rejoin Team Flash? Either way, it appears that Stephen Amell’s wayward cousin will come back to the Arrowverse at some point — it's just a matter of which side of the law he will be on.

2. Is Hank Henshaw Really Dead?

During the first episode of Supergirl, the head of the D.E.O. was introduced as Hank Henshaw. This name instantly raised eyebrows of fans of DC Comics. In the comics, Hank Henshaw is one of the most powerful villains in Superman’s rogues gallery, known as the Cyborg Superman.

In the time following Superman’s death after fighting Doomsday, four heroes rose to take his place and carry on his legacy (Henshaw, Superboy, Eradicator, and Steel). One was not really a hero. Hank Henshaw wanted to impersonate Superman until he could begin to tarnish the image of the Man of Steel and eventually ruin his reputation. Following Kal-El’s resurrection, Henshaw was defeated and has returned on several occasions to wreak havoc for Superman and several DC heroes.

Why would Greg Berlanti choose that name for his director of the D.E.O.? After all, he could come up with any name for the disguise of the Martian Manhunter. With a convenient “death” that yielded no body, Supergirl left fans with feelings of doubt about Henshaw’s apparent offing. Throw in Project Cadmus (who just invented Metallo). who could be holding both Henshaw and Jeremiah Danvers, and the possibility of Cyborg Superman making an appearance is an almost certainty.

1. Will Hiding The Black Siren Come Back To Bite Team Flash?

Team Flash's dark secret may come back to bite them.

The biggest mystery during Season 4 of Arrow was the identity of the person in the grave. After several months, fans were shocked to learn that Laurel “Black Canary” Lance was the name on the tombstone.

While her death shook Team Arrow to its core, her loss was also felt in Central City with Team Flash. Shortly after Damien Darhk ran her through, her evil doppelgänger from Earth-2 arrived and attempted to help Zoom take over the city. After a tough fight, she was defeated and captured by Barry Allen and put into the particle accelerator prison.

Upon her imprisonment, the team wonders if they should let Oliver and his team know about their newly captured villainess. It is decided that introducing them (Team Arrow) to Laurel’s evil twin would be too hard to handle while they are still mourning Siren's heroic doppelgänger. While it is assumed that she is still in her cell (even after Barry’s two resets of the timeline), it is unknown when she will make another appearance.

The fact that Team Flash asked the question about informing Oliver’s group would suggest that Green Arrow will eventually find out about their prisoner. What will Oliver’s reaction be to this big secret? Will it drive a wedge between the two teams? Can she be rehabilitated and become the new Black Canary? Only time will tell if this loose end and the others will be resolved in this season, or a season to come.

Of course, these are only some of the questions we have going into the newest season of the Arrowverse shows:
