Any excuse to gif the boys.
Since Wendell and Wild's main theme is imprisonment/being under someone's thumb, I find it interesting how the demon brothers unwittingly trade one 'parent' for another - they mean to break free of Belzer's control but become subordinate to Bests without even thinking. 'We gotta tell the Padre' etc, waiting for his cues, and so on. It's a more equal footing than they had with Belzer but it still leads them to trouble - and to the Klaxons, who they clearly have bad vibes about, but since they spent their whole lives as lackeys they don't take initative.
You could argue they're Kat's personal demons and that they'd end up 'her' lackeys, but going with the movie's themes I think it would've end up that way. I like to think they help Kat in the end because they want to, and they end up as her friends rather than her minions.
bonus:
This is such an interesting speculation.
Do we even fully know if they knew how Best died? If they did, why would they trust a guy who's crawling back to the people who killed him?
Then again, the demons have shown to have a really nonchalant reaction to death, most likely because they're supernatural beings who've never had to deal with the fear of mortality (unless it's their own of course)
As for them and Kat, let's not forget that the moment they met her face-to-face, they tried to hug her and momentarily forgot they were working with the Klaxons. Still, even when they were flat-out lying to her, they still had this playful attitude towards her.
Jordan himself did say in that one article that the brothers represent parts of Kat, with Wendell being her anger and Wild her guilt, and together they match with her rebellious nature, so maybe there's a kind of supernatural bond at play.
Sometimes, our worst traits are also linked to our biggest strengths.
