just musings
When dave asks thanatos to knock him out at the vault it also causes roswell to collapse. Thanatos's noise only works on thoes programed into the vault. On Sals route dave collapses after getting a password and Sal is completely unaffected.
Dave and Orlando are affected because of their fathers in the vault, but Roswell shouldn't be in unless he's a hammond. I think Florencia is Roswells mother.
In one of the bad path Florencia says she's only trying to save one person and will roll the dice repeating the experiment as many times as it takes.
Thanatos's master is also only intrested in saving one person. Dave is the only person who hasn't died in the vault yet (except from orlando's vission but that still hasn't happened yet) and instead it is everyone around dave targeted starting with whoever he is closest to.
If Florencia is Roswells mother you would think she would be trying to save him with what is in the vault, but she's the only one with the vaults password and she clearly never gave it to him. She could also just go and get the cure from the vault but purposely doesn't. So she must be trying to save Oz since he's given up living since the experiment gone wrong (which Sal was the only survivor).
Roswell is the only friend who thinks he needs to save Dave from himself, he also has knowledge about the house and its secret passages which he shouldn't know.
