Say what you want about the believability of the show's premise or some of the things that Michael does, but this show is beautiful when it revisits old characters and storylines. Quinn (the dead psycho agent in the well) was a very smart man, and good on Nick for thinking of going back there. I was half-expecting Quinn to still be alive and grab LJ, but Quinn writing Kellerman's real name on the wall of the well was just as cool.
Even though it wasn't meant to be funny, seeing Sucre, Michael and Lincoln all locked up in the SHU made me laugh. How good of a job did Sucre actually do? Jeez, there was no sign at all that a hole had been filled in.
I LOVE that they brought back Haywire and the way they brought him back. How was Michael going to get out this bind? The twist was unpredictable (to me) and brilliant.
Michael punching the wall made me wince. That was brutal stuff.
