So glad we get this show in the UK.
I loved this episode. It's not as good as Breaking Bad but that's my opinion. However it is certainly the best show on right now. Here's my thoughts on this think the common blood group thingy is because Ressler is Red's son as they said how rare the blood group is. Bit of a Star Wars episode iV moment a while back between Elizabeth and Ressler... I'm thinking they are brother and sister.
