10/20 headsup with similar hand just earlier

[Morrek]

Villain is Ralf_E on partypoker. Don't know anything about him, he might be one of you guys I dunno. Plays tagish at 6max. Pretty early into our headsup session(only one table because everyone else left). I think he thinks I floated him a couple times w/o showdowns but at ring games(we're on 3 tables, 1 headsup) and maybe once or so at headsup.

This hand was like 3 hands earlier:

If you say fold, what's the worst hand you'd call with?
