You're missing a small step. Sounds like you got the porn date. Now you just need Lin to meet you and Alex there. Try talking with Lin on Sunday morning. I would keep Alex at corruption 5, as it's a bit easier.
Oh shoot, it's actually Lina's corruption I am working on. It seems as though I got her to become corrupted to level 1 even though the two checkmarks for the ones listed above have not been crossed off. I guess I must have done something in the previous rounds that fufilled those quests. THanks
