2 interesting bubble situations am i asking to bust 4th?

[futuredoc85]

In this one im looking at an almost certain bubble if shorty doubles, and big stack is calling me 100% so only shorty>bigstack>me ends in heartbreak here. Is this ok?

Here's another sort of similar one, not quite as desperate this time but half my stack is in the blind next hand and odds are 100% im getting pushed into. My thinking here is if i limp BB will put me in. He didnt, but i felt sure i was either ahead of one of them or the BB had us both beat here. Is this one better/worse than above?
