Oh, sorry for so much posts in a row, this is the 6th now...
I don't think slaini or NS are scum now, if I think about it. Both NS and slaini were viable kill targets for last night, and if one had been killed, the other would have no neighbours. One could have killed the other without being suspicious themselves as much as usual. Instead they decided to kill Drezi. Drezi whom had been scumread by NS, and hadn't been scumreading slaini either, past saying he'd change his vote if it was needed. Sure, he was basically confirmed town at this stage due to his persistance to stay on the AT wagon unless something drastic changed, and also the fact Jess/Ace would've never performed the NK if Drezi was scum, due to Drezi having no neighbours, but it'd have been better for scum to have waited one more night and got rid of a higher priority target, if it was one of those two.
