this is when Yang showed up to save his brother
from the witch

the witch then tells him to come over to her

but Yang knows better not to but he is scared
he is holding Ying in his arms in his lamb form

the witch wants to have them both for dinner

but Yang had to do something to change his brother back

so he had no choice but to kill the witch

after he killed her Ying changes back to normal and they leave her house

but Yang will not ever forget he just killed someone
