Most Memorable Scene: Maia Roberts vs Heidi McKenzie (Shadowhunters)

It's been a while since I've watched Shadowhunters but I remember this fight between werewolf Maia Roberts and vampire Heidi McKenzie in the episode To the Night Children (season 3 episode 15). During the third season, Heidi was a non-stop terror. From holding vampire Simon Lewis' human family hostage to trick him into feeding/killing them to murdering people to manipulating other vampires into killing werewolves (Maia's pack) and so much more. She somehow convinced the Shadowhunters that she was innocent in the werewolves attack and turned in other vampires for the crime. However, Maia was there during the attack and knew Heidi was responsible, so she took matters in her own hands and sought revenge.

Whether this was a right or wrong approach, Maia wasn't going to wait around for the Shadowhunters to finally realize all the terrible things that Heidi was doing. Heidi's overconfidence played a big part in her death because she assumed since Maia was alone that she would be easy to take out. But she underestimated Maia and see how that turned out for her.
