Walter and Nina?

[rsulliv3]

I think maybe Nina and Walter had an affair. I wondered why peter's mother, on this side, was weird around walter, "i worry when you're not here" she said to him and at times wives say that to their husbands when they think they're messing around. What I'm thinking is that walter had an affair with Nina and that is why things are a bit off between walter and his wife.

John Noble said in an interview (you can find the link on the spoilers for EP. 18) that they wouldn't go to in depth about the Nina/Walter connection until next season...which gives us a long time to speculate

I always suspected that they knew each other way way back , turns out I was right .
I think Walter doesn't want anybody to know that he knew Nina , that may lead to some questioning by Liv , that would probably lead to him telling her the truth about Peter , but that's not an option since he told her the truth last night .
I don't know what's up with Nina and Walter , but I'm sure it's awesome , we'll just have to wait and see !

Enjoy guys !

I totally agree! Yay! Fringe in 2 days! So we will find out soon
