Dumpster Baby 2: Mac And Dennis Become Parents by me0wer
Fandoms: It's Always Sunny in Philadelphia
25 Jan 2026
Tags
Summary
It's just The Gang's luck that they'd end up discovering yet another baby in the dumpster at the back of Paddy's. This time, instead of attempting to exploit the baby for money via tanning, or hallucinating a story in which the woman you have been actively stalking for years has conceived a child with your friend's (non-biological) father, they do things a bit differently. And by a bit, I mean a lot.
Or,
Mac and Dennis adopt a baby and, of course, Dennis realizes his feelings for his roommate simultaneously.

“Mac, I don’t... I don’t think I can. Isn’t there something else...?” His voice is shaky; Dennis wants to kick himself for being this vulnerable, even if it’s just Mac. But he might be dying here—emotions are high.
Mac grabs his hand and walks him to the bathroom like this is nothing. “Just try, dude. The longer you wait, the longer the poison will be in you. I can help you if you need it.”
“Help me?”

Dennis accidentally drinks something he’s not allowed to, and he needs Mac to help him get it out.

Summary
Mac moved his hands widely and then gave up, putting Poppins down. “Charlie made fun of my cologne--”
“Perfume--”
“What?--Don’t answer that, Charlie made fun of me because I was wearing cologne and I didn’t want you to think that it was--” Mac wasn’t sure what he meant to say. He had simply started talking, no goal, pure panic.
“Stole it?” Dennis said at the same time Mac finished “A faggot.”
Dennis choked and then laughed “What? Why the fuck--”
“Why else would I be wearing cologne?”
Dennis hesitated again, squinted, recalcuted “Many more reasons than you being gay, Mac.” He laughed, softening. “So you are a faggot?”
“No! I stole it!”
“But then--”
“Dude.” Charlie said, passing Dennis the joint he had just rolled. “Move past it.”Or,
5+1 Mac and Dennis through the years. How long can it take two codependent losers to finally accept they make each other happy?Series

Summary
Mac struggled with his faith since he was a boy; he would plead to God at night in his bed, begging him to break his arm or give him cancer just so his parents would pay attention to him. Now, all grown up, he would start to question - not his requests - but how he never got a response. How every night he prayed to his wall of crucifixes, he would plea to a man who gave him nothing but silence.
