im gonna leave a whisper here, ive been perusing ten little rooster theories trying to figure things out and i liked yours alot, and i thought id leave my input here. i dont think gavin is next, but rather chris. gus mentioned that he was constantly tripping, and i think they meant for gavin to be the obvious choice to fool you. what REALLY got me on that one was how it said "eight little roosters, two others in heaven" and i think that bit was a clue to dispel the gavin thing, saying that (pt1)
(pt2) only two had died, not three (the clone). the life imitating art one that you thought might be chris, i think might be referring to lindsay. one of the murder weapons listed is crescent rose, life imitating art could refer to rwby. i do agree on barbara as the killer though, it would only be too fitting of her to kill WITH a pun. still stuck on 8, 1 and 4 tho
I've gone over theories with several other people, and my friend Michelle gave me one that makes sense. I think Chris is going to die next, too. On the "five little roosters" part of the riddle, it says ONE got trapped and ONE ran out of air (something like that); so that makes me think that that's going to be Gavin because why didn't they just say "ONE got trapped and THEY ran out of air" or whatever?
eagererudite makes me rethink my priorities tbh. xD
