How do I unlock the Christa scene in the DLC?
You gotta do Ymir, Jane, Sasha and Annie first. Then when you wake up again, MC will say it's only Christa/Elsa/Mikasa left. Then focus on Christa.
I am also right at this sceen, but stuck. No more new conversation option show up :-(
edit: nevermind, I think I got the trick now :-)
