Too many alternate channels for your TV.
Though after seeing that chant all I can think is a few years post series Megumi's roomate summons Urd as Caster (she swiped one of Megumi's outfits and it had Urd hair on it), said roommate it utterly baffled by how the elaborate cover story she had thought up was obliterated when Megumi explain Urd was her sister in law. Urd was a viable candidate due to a recent temporary demotion and is far, far more intrested in screwing with Shiro's love life then anything else. Urd uses the chant of doom after the duel between Shiro and Gilgamesh to swarm goldie... him being a threat to her fun and all. The angry one is dragged out of the Grail and then dragged off by Mara, he so did not have permission to end the world and Hild decides screwing with Shiro's love life is going to be a mother daughter bonding event. The uncursed wish is granted when Shiro attempts to figure out what is going on at that point... and now he doomed to understand what is going on in his life without being able to tell anyone or get out of it. Urd disappears at that point, only to pop out of the roommates Tv... and the roommate get paranoid as she is now dealing with Urd without command seals.
