600NL - Set with a lot turn action

[Borsig]

I have a feeling that vallian has been floating me a bit this and he has been a bit more aggresive than his stats shows. I know he is capable of making moves.
He is playing 21/11/1 over 400 hands - I play a normal TAG - 20/17/4.5

I know the J completes some straight draws but I think there are so many two pair combinations he could have.

Any comments is much appreciated.
