Changed Locks and Crossover Fic

[maire78.livejournal.com]

Hi, I'm trying to track down two fics i read a while ago but can't remember where.

1. In the first there was scene in which Brian has either changed the locks to the loft or bought a new house  and Lindsey is shocked and annoyed when he tells her only he and Justin will have keys and refuses her a copy.  (It's definately not Wrens'  - The Experiment though, although i love that one too)
    
2. The second one i'm even more vague on (and hopefully i'm not imagining it or mixing it up with a different fandom) - What i think i remember is that it was crossover - possibly with Deep Impact or Stargate - in which either Brian or Justin win/earn the right to be saved from an impending worldwide disaster and choose to take the other with them.  I think there is then some kind of confrontation with some members of their familes who think they should be taking them instead.

Thanks in advance
