A Jolly Red Lie
Why a red suit? Cause it's christmas, and someone's been naughty. But also so that people don't know he's bleeding, that he's hurting.
In dp2, Wade says he should have worn his WHITE suit when he meets Juggernaut. Because a red suit hides blood, a white suit hides that you're excited, that you're enjoying all this. That you're getting off, that you want it.
A red suit shows you're enjoying it. A red suit doesn't show you're hurting. A white suit doesn't show you're enjoying it, but it does show you're hurting.
Wade's first suit was white.
He swapped it to red because he didn't want to show he was bleeding all over everything. You know, like a bleeding heart. He doesn't want people to know he cares so much he'd sacrifice himself over and over. Selflessness. He wants it to appear as if his actions cost him nothing. He can't have anyone thinking he wants to be there.
But the red suit does show he's enjoying it. Enjoying the fighting, the killing, the being stabbed.
When we first meet pre Deadpool Wade, he was in a red coat, white shirt--the Golden Girls shirt. He's enjoying what he's doing.
Wearing his heart on his sleeve. Showing what he cares about. Told pizza stalker girl he does it for the hugs, and then covered up by turning it into a joke "for the money"--(haha the deadpool movie was ostensibly jokes for money, but we all know that's not true)--and then later refusing to take payment. He's being open, even if he knocks it down a peg after the fact.
Looking at Vanessa with open care, and letting her see. Openly saying things like "Happy holidays", without being sarcastic about it or negating it.
But he stops doing that after Francis. The only time it's shown is when she tells him she wants to have a kid--even then it's still not openly, because it's hidden behind jokes. He doesn't tell her he loves HER, only that he really wants a kid: but DOES HE?
No. He's pretending to care, to want. They first intend to "watch some porn and show the bed who's boss", but we cut to them watching Abjectly Not Porn. He then says he wants a kid again, but the way he describes it is to "get the strap on": that's not how kids are made. He didn't want that in dp1 though: he says "no" to the strap on in the sex montage. (That was on international women's Day. When Vanessa is dead in dp2, it's always international women's Day there. Aka, Wade doesn't want to be there. Why is he there, then? Because he thinks she wants that.)
He's pretending to care about something he doesn't. He's using things he's supposed to want, but no longer does, to act like he cares. He wants to, but he does not. He says he wants kids as he's selling used cars, but that's a lie followed by the offense of "not having vaginal sex". Because he wants to get pegged now, which is extremely offensive to Disney.
So what changed?
