I don't suspect Kelly would be so charitable. In the most recent update, poor Evan looked like he hadn't slept last night. It would be the least Kelly could do to stay at the hospital and let Evan go back to his parents' home and get some sleep.
Edited to note @cereality's update regarding the BBQ. That could have gone on without Kelly. Sure, Gil's the pastor and has to be there, but no one would have batted an eye if Kelly took off after the service.
These people are despicable.
