AcTh vs. 5h5d2h

[J_B]

Just had joined this table. After the flop the SB took quite a long time to act. At this point I'm 70% certain he doesn't have a 5. I believe he either has a flush draw, over cards such as AK, AQ, or something like A2 or maybe K2, etc. On the turn I'm a bit more certain this guy has A2. But, not enough to bet into it if I'm wrong. Should I be betting here?

What's your move here?

I'll post the results later, if you like.
