They get to a turn card once, where Thang takes it with a bet - now they're seeing quite a few betless flops, and turns... I think Thang is whittling a few chips off Ben, but no drama for a good while now.
Sudden rockiness perhaps a little unexpected, but I think after Ben's double through he's not in a big hurry to be all in and called again.
flop, for example - Thang checks, Ben bets 45k, Thang folds.
There you have an absolutely typical example of the hands from the last 20 mins.
