I think it's most likely that she'll return to Maki in a fit of anger and tears, bitching and whining and demanding to be comforted, and Maki will hug her, pat her on the head and say: "There, there, poor Liz, poor baby, you've suffered a lot."
I beg to differ.
As you may or may not remember, Liz has never revealed to Maki her tragic past. Certainly the author wanted to save that for a special time.
Because that was the one time when bad things happened and Liz can absolutely not be blamed for anything. Senpai romanced her, won her heart, used her, and betrayed her. Liz is 100% the victim and senpai 100% at fault.
Liz will return to Maki, yes, of course; but not to bitch at her. She'll tell her that senpai is the real bad guy here, who hurt Liz in the past and hurt both Liz and Maki now. Maki will be mindblown by the revelation, the secret past of Liz and senpai's villainy, and their reconciliation will naturally follow. I'm so sure of this I'm taking any bet.
