Ryan and Sergey are life partners?

In Ryan's book he addresses his bi-sexuality, but I am not sure he mentioned anything about Sergey being a life partner. Someone mentioned a DVD extra on another thread that eludes to the two living together and sharing a pet dog. Maybe someone else can answer you.

I'm no sure about serg being his partner but he even confirmed his bisexuality on his twitter so yeah he's Bi... I kind of knew it anyways but it's nice to hear it from himself ^_^

"the apple doesn't fall to far from the tree, unless that tree is on a hill".

Well when they hugged in one of yesterday/last night's episode when he hugged him before he went to the tower Sergey did something a little extra like rub his back. I always knew there was something between those two...but I don't think there is anything bisexual about Ryan. I think due to him being a Roman Catholic it's hard for him to say he's gay. I believe that's why he likes having Chip around to help him with both his beliefs.

So my opinion is that they are a couple.

Don't know.

I read somewhere that one of their personal notes/writings were discovered where it was written that they had "tasted" each other, and mentioned the joy of being in such a great relationship.
Not sure which one wrote it, or if it's just fictitious.

In one episode either Ryan or Sergey was playing with flour with one of the female team members and (I think) Ryan got hit in the face by Sergey, and Ryan grabbed some flour and threw it at Sergey, Ryan then licked him the side of his face and said something like "no wonder that a love you so much".
