I struggled with this decision point a great deal for a couple reasons - and not buying or selling the choice of action, just explaining:
1) what did this card change that caused UTG to put out a strange blocker looking bet out of position? A4xxx with ace of clubs flush draw? A high hand like 10JQKA or something similar, potentially also with a club or spade draw?
2) maniac is super aggressive and loves putting people in bad positions, but is also not a total moron against multiple players - if he was pushing a set of 10s, spade draw, a45xx type of hand does this card slow him down or does he keep piling it on?
3) "top set" is overrated - there are many combo draw hands that are even with me or potentially ahead with a large number of scoop outs - and my nut low draw may be in line to get quartered or even sixthed multi-way - not any cards other than a jack, paired board, or red 5 I actually want to see on the river. And a 10 may bring someone quads.
4) mentally, being in the game for a little over $200 and clawing my way back, I did have that "I don't want to lose all my work on what is not going to be much better than a flip, and I could be behind"
5) my club draw multiway is likely blockers at best
So, I called, and figured maniac might handle the aggression for me.
