I fully understand William's desire to kick them out as soon as possible, imagine - strange people teleport to your house, ask for overnight accommodation and also bring trouble while giving nothing in return. It would annoy me too.
William: "You DON'T know what i'm capable tod ot o you." Frisk: "Have you killed an entire race amd erased releality before?" William: "Uhh... No...?" Frisk: "Have you foght a God-Like flower noghtmare fuel tgat can summon nukes and giant flamethrowers and won?" William: "I... I don't think so." Frisk: "Have you managed to survive a literal god that is immortal and almost omnipotent, with enough power to literally devour the world?" William: "Wha- Obviously not." Frisk: "Have you came back from death countless times to the point where you can call yourlsef immortal?" Willial: "I didn't...- Wait, THAT i did! I always come back from death!" Frisk: "Then, when you do the other three things, maybe we can talk."
Bonus: Chara:well i gtg now frisk already is gone soo yea cya Cc:oh okay goodbye Chara:*teleports to frisk* Cc:well shit guess i have to survive tonight again The end😃😃😃
Elizabeth will 100% not do that,she wants to make her dad proud so as she saw William didn't like them here she will actually also try to kick them,and she will most likely try to kill Frisk to make her dad proud,of course,if her dad didn't do It before her. That's all-
