[rewritten to actually match the character's syntax]
Fred: Now, let's see who this so-called spider goat really is. [takes off mask, revealing Milo's face]
Fred, Daphne, and Shaggy in unison: Milo Yiannopoulos?!
Scooby: Rut?!
Velma: I knew it had to be Milo when, after clobbering Daph, the "spider goat" ran off blushing into the men's bathroom. He's the only one here sexually repressed enough to have that kind of reaction.
[Daphne crosses her arms, muttering "creep" to herself]
Shaggy: But, why would Milo want to wreck a video game conference?
Velma: That's why this whole thing started on the last day. It's not the video game conference that Milo wanted to ruin. He wanted to scare off the "women in tech" conference that's happening tomorrow. Nobody would be suspicious of Milo being at the video game conference, but if he tried to attend tomorrow's conference, he would have been kicked out before he could even start using his "spider goat" gimmick.
Milo: Gimmick?!
Policeman: Well, where he's going, men and women get their own separate prisons, just like you'd want it.
Milo (muttering to himself): And I got caught by a girl, too.
