My first 'excellent' vote for some time. Loved T-Bag's inner conflict, which I found credible. He's always been a slightly complex character and sometimes is as reluctant to kill as he is happy to do on other incidents. Plus I knew that that salesman would have more to him than meets the eye - he was played by the serial killer from Journeyman and the Everyday Dad who killed a terrorist with his bare hands in the last season of 24. So he had to be watched!
The 'Re-take Scylla, then lose it again' is getting a bit annoying, a bit like the way they keep losing then retrieving the nuke or nerve gas weapon etc in the last few seasons of 24. But with Michael being captured by the Company (didn't you think Linc would get there in time? I did!), Mahone being led off by the Feds, Sucre getting his ass kicked by Gretchen (actually, I thought she would do that all right!), the episode was far from predictable. Still can't wait to see what happens next.
