Check-up hand - TPWK from BB in 5-handed pot

[Absolution]

I'm having a hard time thinking of a card that comes that makes me fold this. I'm committed to a showdown at this point unless I had a read that he was passive. My read here would matter more than the card.

I could see checking and calling down any A though.

What about a diamond, particularly one that also completes a straight?
