Last 20 out of 132 players, entry is €100, we hold tens in BB having 41 big blinds.
Bubble is 13th position.
7 players are at the table, CO (cca 350k stack) raises to 20k (blinds are 4k 8k, ante 500) , SB short stacker (cca 50k) just calls 20k (??).

Are we going to complete to 20k and play flop 3-w or we will isolate SB knowing SB has either super monster (trapping - which I doubt) or he is weak (in holdings and as player)?

If we just call we reduce potential loss, but any broadway OTF could make our hand super weak, we could easily be bluffed, especially by shorty one. We lose oportunity to knock CO out of hand, and to play vs weak SB as I see the situation.

On the other hand, if we raise to cca 55k, we could be called (same problem on 1-2 broadway cards flops vs CO) or maybe reraised if CO notices what are we doing here...
CO could easily jam w/ AJ-AK, I think his rereraise to cca 125-140 would be w/ (KK, AA) - we fold then. What if he shoves after we isolate?

What would be your option here?
