I've seen some 0.3AF types makes some slightly weird raises before. And obviously he can be cold-calling PF with a fairly wide-range given his 40/2-ness.
So I'm thinking that it's possible for him to get frisky here with 9s7s or Js9s on the turn. Or even something silly like AT or As8s.
It could even be something as ridiculous as 32 or 43 in which case you have plenty of outs.

I just can't trust a guy with such passive stats to be choosing the right times to slow-play or raise because he's already so ridiculous.

This might be calling-station-monkeyish of me though.
With an AF of 0.3 there's a decent chance you are just drawing to your 2-outer obviously.

But even if the chances of your JJ only having 2 outs are fairly large it still means you have a 23 to 1 shot and are getting pot-odds of 13:1. Not enough odds on its own to warrant a call of course but at least it's something and when you combine that with the slim chance that you are still ahead and/or drawing to outs to counterfeit a 2-pair somewhere in there and I think a call is okay.

Also, when the SB donks the turn I think I'm raising again here.

It's a weird hand and I think you can hardly be blamed for folding given the dude's AF but I might be able to make enough excuses to spew some more of my chips to him.
