Now that we have a regrettably long hiatus to deal with, I figure we might as well speculate on what will happen following the dramatic events of 'Depths'. So we have Artemis who is disguised and has gone under cover with Aqualad presumably to join Black Manta's organization. We have an entire team and the remaining members of the Justice League who are mourning Artemis' death. And then we have Nightwing and Wally who are in a precarious position of having to pretend to grieve and continue with their daily routine while really keeping the secret of Artemis and Aqualad from the rest of the team and the league. Then we have Lagoon Boy who has been captured and could become another specimen for the Light's partner as Kaldur put it even though he has promised to try and protect him. We also have other captured kids such as Longshadow who are also presumably specimens for for the Light and their partner. There is also Bart Allen and his apocalyptic future which could be connected to the Light and their partner's intentions. But it could be something completely different. And finally we have the core members of the league who are still absent and don't seem to be anywhere close to returning as far as we know.
I feel for Nightwing and particularly Wally because they are in a very precarious position. I mean in a way it is a betrayal of their friendship with the rest of the team to keep such a big secret from them, but the reason is important. I can easily imagine that Wally's going to have a tough time, especially if he continues to stay a civilian. He will have to go through a pretend grieving process while in reality be worried about Artemis' safety which he can do nothing about. I assume that he's going to return to the team because it will allow him to keep better track of what is going on with Black Manta, and also because he will know that Nightwing will need his help to keep such a massive secret from the rest of the team while still keeping their regular work going. I doubt we will see much of Aqualad and Artemis until the last quarter of the season since they are deep cover. Maybe once every 4 episodes. Meanwhile, Superboy and Miss Martian will try and search for Lagoon Boy and along with Blue Beetle attempt to find out what are the kidnapped 'specimens' being used for. There's obviously a lot more going on and a lot of characters who we haven't seen much in action. I presume there will be at least a few episodes after the hiatus where we will see some of the newer characters get some chance to show off their chops before the latter half of the season starts and things get dramatic again. I get the feeling that the season will end with the core six uniting and fighting again.
One of the things that I'm most curious about and have no idea how it'll go is Artemis' role as a mole. Since Kaldur is now a high ranking member in Black manta's organization, I'm wonder what use Artemis will be. Besides, it doesn't seem likely that Black manta will just randomly trust some new girl who has just joined their organization. It will be interesting to see how that is handled.
