But ooh, he got to say "fuck" and "fucking" a bunch of times, be a drunk deadbeat dad, and be the exact opposite of Bobby in every possible way. I LIEK!
But hey! The writers endeavored to write him dialogue that allowed him to say "balls!", which was awesome. And there's a very slender subplot (not related to Jim's at all) that had Dexter saying the following (or similar):
No adult goes by Bobby. It's gotta be a William or a Will we're looking for.
The point is that they deliberately used the name "Bobby" for an expository character, just for this episode, when *any* name would've done.
Yep! Dexter had to kill JIM FUCKING BEAVER! Now Jim can add that to his resume. Not to mention: convincingly and beardlessly playing a misanthropic, alcoholic ex-con with a gambling problem and a history of child neglect who's into verbally abusing his grown daughter and using guilt to fleece her for cash. Jim FTW!
I love this fandom.
