If we're going by the OG lore, Pink was vibing when Maroon came in and killed. Yellow saw and reported. They sing and at the end Maroon is revealed to be behind it when he reveals his mouth when all is against him. Afterwards, the crew and Pink throw Maroon off the balcony and Maroon grabs Pink before turning into parasite form. Honestly this all works really well. Great choice of cast for this cover! It also sounds great!
In the canonical Voting Time, Jelqer and Warchief are partners (I think so). So in this version it would only make sense if Gray, just this one time, were to team up with Yellow.
They searching for who is the crewmates which in this case it's yellow and GREY but pink will skip cause she doesn't want yellow to be ejected that or vote grey
lore (my take): yellow and pink make grey start to feel sorrow in the first time in years, so he stoped killing. Leaving maroon to be voted out by the trio.
