i say Leahs made pietro kills wanda because she manipulated his DNA and mindrape him in the house of m stuff.
Now that sounds like a Leah plot, she spoliers her story...The thing that I honestly like the most about ToM is that Leah Williams is trying to put out this narrative that Wanda needs to take accountability, whether it's past or present Wanda.
Williams says that her writing was interfered with, the movies she no mutant in mcu but pietro peter is magnetos son in the xmen.
wanda know she hurt her brother and she doesn't want to hear the truth
pietro is afraid of her
