I'm sure others already know but I only found this out recently.You can have Lee interact with Ben when he's choosing what to do with the teacher caught in the bear trap,I can't believe that I always missed this in my previous playthroughs!
Lee can talk with Ben 3 or 4 times and try to reassure him(he's panicking,what a surprise!) until Lee finally tells him to shut up and Ben answers back with "screw you man!" and then storms off

it made me laugh.
