They aren't allowed to kill Owen.
So, I enjoyed both the episodes (Adam was a creepy, creepy alien!), but I would like to say, very firmly, that Owen is not allowed to stay dead. Since they've brought people back before, I'm going to believe that the team will bring him back. Especially after the 'I heart you all' thing that Jack did with them in "Adam". He promised to save Owen. I'm just saying. Sure, he was meaning it in a more emotionally-based way at the time, but he still said it.
I really enjoyed Martha in "Reset". She blended well with the team -- had some good ideas but didn't try to overpower anyone and she had chemistry with people. It was really nice. I especially enjoyed her interactions with Owen -- he seemed really happy to have someone there who understood his stuff.
Owen's the character that's gone through the most character growth over the last season and a half, and Burn is their best actor. I refuse to believe that they'll kill him off.
