wow it's always nice to have them open you. that's why we "peacock" dude. you did the photo, you could say hey let me get one with you and your friend in it, kind of showing befriending of the friend.
they've already showed you a couple of IOI's by now it sounds, so maybe move the set to another area and try to isolate your target.
or simply ask her friend if you can borrow her after getting a few more IOI's. do the "friendship test", kino, move in
my personal goal if this happens..... have a 3some with both the girls lol
