One of the fanfictions I am looking for is one where Puck takes Rachel paintballing and Sam ends up accidentally shooting her in the head and she gets hurt
The other story I am looking for is a Puck/Rachel. All I remember for it is Mercedes is really mean to Rachel and in it Kurt goes and visits Mercedes mom to tell her about Mercedes dating with photographic proof because he is upset at how Mercedes has been treating Rachel and later on she shows one of the boys Mercedes has been dating that she has been cheating on him with another guy.
I am also still looking for the fanfiction where Puck is neighbors with Rachel at her apartment building and it is an AU where the didn't know each other in school and in it she gets pregnant from a sperm bank with twins and later comes to find that Puck is the sperm donor.
