($33) JJ bubble vs Big Bully

[Pasterbator]

So i was lost. How short does shorty have to be for this to be a fold? Assume big stack is pushing top 50%. How about any 2? He has been pushing almost every hand since we got down to 4, so any 2 wouldnt be too far off.

Blinds 100/200
Shorty ~400
Button ~1800
Bully ~ 4600
Hero ~ 1200

2 Folds. Bully pushes.
Hero has JJ.
Hero does what?
If i fold, what can i call with?
