Heya! While judging is going on, we don't want to get too, too involved in feedback. But suffice to say you can summarize that Mia owes Arika her life in dialogue, then maybe do a quick flash-sequence with a "voice over" (text over?) showing that it wqas during a vulnerable time, etc. Then, as the game progresses, have it come out in bits and pieces. I could be a comment here to another character, or a small scene there. Just add it up so that the player slowly comes to understand how deep it goes.
