So Mattia finally shows his true colors, I thought he was suspicious but then it seemed like they cleared that up but he really was connected with Ouroboros, that's gotta sting for Barnaby.

his eyes are shown golden, he's probably under control of Ouroboros lady who's definitely not a non-NEXT, same as old man that could paralyze was... probably she figured out that Mattia leaked info that it was Gregory and brainwashed him to show fake guy photo, when it failed, he warned Gregory still being brainwashed...

P.S. IMHO safest approach against Gregory is putting Wild Tiger against him (especially if he will use power beforehand) so when Gregory hugs him, he won't be able to use NEXT powers since it lasts only 30 seconds and he can't use it back to back.

That makes sense, then I guess Mattia might still be trustworthy and his time with Barnaby hasn't been a lie.

Close call it's fun they had to stop being superheroes for a bit so we got a bit of detective play going on here instead :)

"Hug the Gregory"? Really?

Another quick episode
