I honestly didn't have the intention of adopting Christina even if she is my daughter in a sense, at least not initially.
This is because Christina is not really an orphan herself. She still has a loving mother even if her father is no longer part of the equation.
Did I say equation?
Anyway, Xavier will be dealt with appropriately, now that Hydra did a little bit more investigation. Like to where he has been. To whom he has been talking to. That sort of investigation.
I even have a kill squad raided his apartment in secret and all of his things confiscated for analysis. He will not be needing any of them anymore. Quite a lot of sensitive documents were found hidden inside the walls, under the floorboards and in the ceiling above.
They are all classified, obviously.
