Another what would you have done?

I'd cuss, and then fold. I would have to assume BB has a spectacular hand based on how tight it gets when it's so close to the bubble. I'd probably cuss him/her after I'd folded too.
I'd be surprised if they came over the top with less than AK but I have seen it happen.
What's the buy-in though?
I'd say that's an important factor in guestimating the other guys hand.

Sure the play gets tight on the bubble BUT perhaps the BB is exploiting the bubble here & KNOWS that SB can't call unless he has a Top5% hand (although without knowing how deep the stacks are here, it's hard to say). If villain has a super strong hand and had hero covered, would they ship the pile in with a monster? I doubt it... much more likely to 3bet them, hoping to induce a shove.

As tempting as that was to double through the big stack, your best play was to fold. Even if you did not realize the remaining players were at the bubble, continue to play solid it focus on the bigger prize on the cusp, the final table and winning the tournament.
