About not taking Alexander Sebastian with them.

I'm talking about the scene in the end where Dev is taking Alicia to the hospital. He refuses to take Alexander with him and this really blows my mind. Lets analyze the situation shall we.

If they take Alexander with them:
a) Alexander survives and is most likely willing to cooperate in order to save his life
b) Alexander knows a ton of nazi secrets that can immensely help uncle sam, not to mention Dev's career
c) Taking Alexander with them will make it more likely that the other Nazis don't flee just yet
d) Alexander knows what kind of poison Alicia was given. Taking an antidote might be a question of hours - hours which will now be spent trying to figure out what the hell she was poisoned with.

On the other hand, if they don't take Alexander with them:
a) Everyone from the house will flee or be killed
b) Stuff will be covered up, leads will disappear, the investigation will run into a dead end
c) Alicia might very well die, because nobody has any clue what she was poisoned with
d) Dev can privately talk to Alicia in the car, about how much he loves her

It's scenes like these that won't let me enjoy this movie at all.
