Loki season 2 finale’s Ant-Man 3 reference might have just set up Avengers: The Kang Dynasty

gamesradar.com:

Well, the Loki season 2 finale featured a lot of revelations about the past, present, and future of the God of Mischief. But thrown in with all of the emotional arcs being woven together was a very intriguing reference to Ant-Man and the Wasp: Quantumania.

Before going any further, we’re getting into big spoilers for Loki season 2 episode 6 below, so make sure you’ve seen 'Glorious Purpose' before reading on. 

After Loki (Tom Hiddleston) makes the ultimate sacrifice to take He Who Remains' place and hold together the branched timelines, the show skips ahead. In a time simply referred to as "after", we’re back at the TVA with Mobius (Owen Wilson) and Hunter B-15 (Wunmi Mosaku). 

The pair are dealing with the consequences of Loki’s choice, and that includes working out exactly what is going on with those He Who Remains variants. "Do any of them know that we exist yet?" B-15 asks Mobius. Handing her a case file, he says: "Nope. I guess one of them caused a little bit of a ruckus on 616 adjacent realm, but they handled it so we’re all good for now."

This is clearly a reference to the events of Ant-Man 3 because Earth-616 is the Marvel timeline we know and love. That film sees Scott Lang and his family end up in the Quantum Realm where they encounter Kang, who has been exiled by his variants out of fear. 

As Mobius mentions, they do manage to subdue him by throwing him into a power core, but it's interesting to hear this being on the TVA's radar. What’s more, if you zoom in on the screen here too, you can see some case file details including pictures of Kang in the Quantum Realm. 

All in all, it's a really neat Easter egg that could actually have huge implications going forward as we get closer to Avengers: The Kang Dynasty.
