Ah, I thought Britt removed the bullet in Jason. Thanks for clearing that up for me, @Chanandler.
So now we'll have some dumb mystery about who really shot Jason? Maybe it was Shawn, out on furlough and missing the target—somewhere fatal on Jason—again. Hee.
Same. That's fairly in-character for Jason, too. When he likes someone, he doesn't let other people badmouth them.
