Stars $5 Rebuy hand- How to maximize value

[foxfox1]

Villain in this hand had been taken off of a couple of his PFRs recently and is probably getting a little frustrated. Other than that, no reads. Do you ever just call here and give him another chance to go broke or should we be worried about a flush draw/5 outer or do we get it all in here everytime? Thanks
