Tear Jerker: White Collar
This troper can't make it through Neal rescuing Peter in Company Man without crying, particularly this exchange:
Neal: No! No, Peter, we don't have time!
Peter: You can't leave him behind.
Neal: You are dying, Peter!
Peter: Neal! ... Neal, we don't leave anybody behind.
[Neal gives Peter a desperate look and then runs off to save Kent.]
Judgment Day: There was nary a dry eye to be found.... well, there was, but to quite a bit of the White Collar fandom, the end of this episode made them tear up.
The end of Parting Shots. Jeff Eastin's tendency to use titles with double meanings has never been more cruel.
Mozzie's shadow-puppet show in Identity Crisis, in which he tells the story he made up when he was a kid to try to rationalize why his parents abandoned him.
Neal: It's a really great story.
Mozzie: That's all it is, Neal. Just a story an eight-year-old tells himself to hide the fact his parents didn't want him.
This scene is the only time we ever see Mozzie cry.
But it also doubles as a Crowning Moment of Heartwarming, as it shows how good a friend Neal is to him. He insists that Mozzie show him the shadow puppet show, sits attentively through the whole thing, and then comforts him when Mozzie breaks down.
When Neal says goodbye to his father at the end of Family Business.
The flashback to a three-year-old Neal happily telling his dad goodbye as James is leaving for work makes it even more heartwrenching.
The end of In The Wind. Seeing Neal in tears as he begs his father to stay and testify after Peter is falsely accused of killing Senator Pratt is absolutely heartbreaking. The utter desperation in his voice as he pleads with James.....
Neal: You show me you're better than this! You show me you're a decent man!
My gosh, Matt Bomer deserves an Emmy for that performance!
Mozzie kept all of his scheme's connected to his real name. Why? So his parents would be able to find him if they ever came looking.
The death of David Siegel, Neal's new handler.
Peter telling Jones not to volunteer to be Neal's next handler, telling him he'll regret it all while Neal is listening in via bug.
