As far as Gera/Gibus goes
Gera has, at four points in the game, directly quoted and questioned a vote on Gibus.
In posts #304, #945, #1387, and #2181.
But the interesting thing is... I actually think in all four instances the questioning of said vote was
valid
. All four of those votes were poorly explained or outright bad. Though, #1394 is awkward.
Gera makes no indication of actually attempting to sort Gibus until post #1565 when Gibus' train is really picking up.
Gera had a long-winded (albeit underwhelming) miniwall post on #1590 with a vote that directly led to Gibus' claim on day 2, to which Gibus simply replied "nah".
Gera has questioned votes on Gibus, but he's also questioned votes on a lot of people. He particularly does it on multiple votes Alex makes on day 2... Including on BBT. I don't think the defense towards Gibus specifically is scum indicative.
If Gera is scum with Gibus, does Gibus just... Totally blow him off here?
Gibus has now voted Gera twice: Once as a countertrain to Vivax (Following NM, of all people? I forgot NM ever got off of Vivax yesterday) and once today... After Vivax's train died.
A Gibus/NM scumteam would have tried to kill both Vivax and Gera this game with votes. Outside of the recent joke vote from Gibus, the two have almost entirely ignored each other this game, and have never voted for each other. The only time Gibus even appears in NM's iso is in very very early joke posts.
