Oh wait, you did address night 2. You just addressed it in such a hand-waiving, unconvincing way I legitimately didn't realise you were talking about it.

Mafia not killing to try and throw suspicion on town isn't unheard of
Really? That's what you're going with? The toasters have a free reign to murder one of us in the night with no direct consequences, and you think that 'they just didn't do it to cast suspicion'. OK, and who exactly were they casting that suspicion on? All their inaction achieved was either making people less suspicious of Roslin (town), or more suspicious of me because they thought I was in cahoots with Roslin.

But seeing as she turned town when she threw herself out the airlock there was no one for me to be in cahoots with.

I was gunnin' for Dee the day after, maybe the inaction on night 2 was to trick people into believing there's a doctor protecting Roslin and then persuade everyone to lynch Dee? But then... why not just use the 1-per-night free murder to kill Dee rather than this pointlessly elaborate ploy?
