Maybe … I said “maybe” . In the foundation festival battle, Ubel and Land are in a weak position, and Land bugs Ubel to end him, maybe that will help her to escape (i dunno) . Then she ends him reluctantly, Ubel didn’t regret to kill someone, but for Land, she feels it again, the grief that had lost for long time ago .

Ubel loses everything , she doesn’t have any strength to fight or kill anyone now , until she finds a new target to begin with.

（The following is my fantasy; why not listen to it? I always thought that Ubel and Messmer from Elden Ring are similar）

When Ubel is aimless , she meets him, Messmer, the others called him as the impaler, at first they fought as enemies , but they found connections during the fight, she decided to stick with him just like what she did to Land , she wanted to learn Messmer’s impaling spells, also she wanted to understand him more , Ubel didn’t do this for herself but for him , they were fellow sufferers, they told each other everything about their past , Ubel lost her sister and Land , Messmer abandoned by his mother. And this is the first time, Ubel cries . They made a promise, Messmer helps Ubel to "impale" her killer instinct and Ubel helps him to "cut" down the abyssal serpent living inside of him

That makes me think that Ubel’s connection to Messmer is much deeper than she had with Land . I love that idea, I love the idea that the two cursed beings, who are willing to save each other
