Lost - Charlie is my least favorite character on the show, and I hope he is the one killed (apparently one of the main characters will be killed by the end of the season). Still, the idea that he wanted to help someone feel good/safe worked well for me.
*By the way, the backstories for Jin and Hurley, respectively, are coming up in the next three episodes (after another on Sawyer).

Alias - This season isn't as strong as previous seasons for me, but last night's episode set up some great things (I hope). There was no tension for me because we knew Sydney wasn't going to die or stay insane, but it was a great plot for letting us in on Sydney's inner fears about Vaughn and her father. I also loved Dixon's speech to Sloane, and surely that sets up some stuff for the reason of the season.

"Every element, from the masterful picking to the gorgeous,
keening vocals and a song selection of tremulous grace,
thrills with authenticity and emotion..." - Entertainment Weekly
