Ok so I have a headcannon I'd like to share.
I like to think that Jorgen has a secret soft spot for both Cosmo and Peri but doesn't want to admit it. Ever.
Sure back in Cosmo Rules he hated the idea of being related to Cosmo and there's no doubt about that. But I like to think that over time (which is who knows how many years) he's warmed up to him, mostly because Cosmo has a way of getting into people's hearts with his good nature (despite being dumb).
I like to imagine that he's not really used to hugs, so Cosmo giving him one really shocked him and he kinda liked it. But he definitely hides it behind his toughness.
Also in FOP ANW, in the "Haunting of Wells House" episode Cosmo says he contacted Jorgen to get rid of the fairy ghost.
Sure it could be played off as they needed someone else to help and he was being kinda dumb by calling someone from Fairy World, but the fact that the show runners let him explicitly state it gets my mind thinking.
Then there's the relationship with Peri. I absolutely think he likes Peri a lot more, considering he's such a stickler to the rules (not to mention smarter).
Which kinda makes this moment here a bit more sweet.
I also like to think that his caring side to Peri will show up a sometimes but only in private. Which would explain why he calls him Peri-Weri here when it's only his parents, Dev, and Hazel in the room. He for sure wouldn't do that in public.
So yeah sure, he's the toughest and strongest fairy, but he cares about his job and his family. It's just that he hides it under all his toughness. He's gotta keep his persona because it's important to him, both in and outside of his job.
