EXCELLENT issue. I don't feel like typing out a whole detailed breakdown of the issue, but basically we are threatened with Kree/Skrull War 2 as both factions want to take Teddy - the Kree say that as a Kree he is obligated to join the Kree army, and the Skrulls want to take him back to reign as he is royalty. Or at least the Super Skrull does, who is surprisingly a pretty decent guy.
So yeah, it is confirmed that Teddy is half Kree (Mar-Vell) and half Skrull (Mar-Vell's tryst with a Skrull princess)
It is also confirmed that Billy and Tommy are in fact Scarlet Witch's twins, or rather reincarnations of them. When they were removed from reality, Mephisto took control of their souls, and when SW went kooky she apparently destroyed Mephisto and their souls were free, and they were reborn I guess. GREAT explanation.
4.75/5. It says it will be concluded next issue, but is that the series, or just this arc? I don't remember if they said this was only 12 issues.
