Weirdo QQ Hand From 2+2er

The following hand was posted on 2+2 and I think that it is worthy of highlighting. What on earth has UTG+1 got here?? Going by the Hero’s reads he has nothing to worry about with the SB donking, but is UTG+1 really flatting like JJ/TT here?

“Probably standard, SB sucks running like 35/8 over 30 hands and UTG+1 is a 18/14 reg not much history past 3betting preflop and raising c-bets. SB donking range is prob rather large here consisting mostly of overpairs to the board, but the flat by UTG+1 concerned me.”
