[Spoilers] Mahoutsukai no Yome - Episode 18 discussion : r/anime

The episode highlights a significant change in Chise and Elias's relationship. While Elias has previously been the one protecting and teaching Chise, his lack of emotional understanding leads to a "rampage" that Chise must now manage.

Chise casts a powerful "lullaby" spell on Elias that puts him to sleep for four days. Because she is the one who cast the "lock," she is also the only "key" who can safely undo it without breaking the magic.
