Title: Admiration and Familiarity are Strangers
Fandom: Rugrats / All Grown Up
Pairing: Past Tommy/Chuckie; Dil/OFC; mostly gen
Rating: PG-13
Word Count: 3,100
Summary: Chuckie Finster, age thirty six, leads a pretty awesome life as an astrophysicist. Until the day his quiet lab is turned upside down by the arrival of a filmmaker visiting for research, that is.
Notes: This is, as usual, for dancinbutterfly, and is also the fic that assures I will be driving the bus to hell. Allow me one moment to preemptively apologize to your childhood. Thanks to afullmargin for the beta.
Warnings: This is not the fluff you're looking for.

( With Dil standing there, vibrating like a happy puppy, Chuckie decides he has to make some kind of physical gesture of continuing friendship, even though that's not really the case. He finally settles for offering his hand, but what should've been a shake turns into a manly one-armed hug, and quite frankly, the whole thing is ridiculous. )
