So this is a very different game than the blitz games I've been playing lately, but I find myself in the oddly familiar position of trying to sort a small number of town players from a larger group of scum.
1. MiX-
MiX seems to have a very confrontational playstyle, and seems to tunnel quite strongly, which I think are towny traits, but fakeable by talented scum. Based on the interactions he's had throughout the game, and the way that he's played today, I certainly don't see the possibility that he's anyone's partner on a scumteam.
2. Ash-
If there's one thing that I know about ash, it's that cranky, disengaged ash is town!ash, and that him not wanting to divulge information about his role is very much in character for him. I also know that he would know to do the same thing as scum. I would believe an ash/didds team, but I don't think there's any other ash team that's plausible.
3. Space-
Confirmed not Marquis (barring bus driving shenanigans that aren't actually plausible), so not someone we should consider lynching today, if I undestand all the math correctly.
4. WCD-
WCD is always difficult for me to read, but I do know that she is adept at emulating her town meta as scum. My scumread of her is largely PoE, but I do find the claim here suspect- the way I see it, there's actually a lot of utility for scum to claim here, because it diverts the lynch away from you, and a mislynch here puts the marquis in a strong position. Of all the possible partner combinations, her and raerae and her and ash make the most sense to me.
5. raerae-
Her tunneling of MiX all game, up through today, reads as somewhat fake to me. MiX has been a controversial player who nonetheless has had enough people defending him that his lynch was never really viable; I think that continuing to push it is a good cover story for scum, as it lets them look active without having to get their hands dirty in mislynches, and then at LyLo they can come out with "I've been pushing this all game, lets's make it happen". I'm not sure if this is within raerae's scum meta, but it smells fishy to me.
The problem with the scum!didds scenario is that with her power (I'm assuming she's telling the truth about that) we have to decide between wasting a lynch on her or trying to hit her partner. I have thoughts about who might be the SK but I think it's best not to voice them.
tl;dr: MiX is a bad lynch today, I would vote didds or ash or raerae.
