Hallelujah!!!
I was thinking that there would be no plot point in Pam having left to go find him, if he wasn't going to survive. My guess is that she's been nursing him back to health in the 6 month interim. (I do not want to see a semi-recuperated Eric next season, like Russell Edgington after being buried in concrete...wait until he looks good to bring him back!)
I was actually disappointed that Eric took off for leisure time in Sweden. I thought he'd left the camp to go help Sookie with Warlow, since he was able to get through to fairy land and drink Warlow's blood. Kind of disappointed that he left her in the lurch instead of helping...but Bill was redeemed instead.
