Before Loki premiered, the Marvel Cinematic Universe's Phase 4 was an expansive phase because it introduced interesting characters like Shang-Chi and the Eternals. But after Loki's finale, things exploded as it officially brought the multiverse to the MCU and its most dangerous threat of all, Kang the Conqueror. Now, with some time having passed and more movies and shows, Loki Season 2 will see the aftermath of a multiverse born anew and how this has created many benefits and even more problems. One of the best examples is Sylvie, who was an ally and enemy of Loki.
