Kinda what I meant about his expositional monologue. "I've been called many things... Conquorer..." was slid in there. Also, with his little animated action figures, when they began fighting eachother, with the battle armor instead of the "peaceful" versions of him with lab coats, it was clearly Kang. But outside of hardcore comic fans, people don't know who or what Kang is, and this did a masterful job of keeping that a secret in the bounds of the MCU.
Also, one thing lost in all this that I'm sure will be addressed later is the fact that The Tessaract is still at the TVA, which means our known and established MCU timeline is fucked up and missing an Infinity Stone...
unless when the TVA reset the timeline, it actually forced the ending to the original Avengers where Loki never escaped...

"Here's the thing: multiverse theory's a BITCH!"
Anyway, here's another prediciton: after everything gets resolved, and Loki gets back to where he's supposed to be, he's going to pull the same trick "Lonely" Loki did to get around being killed by Thanos. What he does with that remains to be seen, becasue even though he seems to be growing as a person from all these hijinks, everyone from the actual timeline only thinks of him as they know him.
