So, I'm here with a probably stupid question but curious as f.

One of Furia's kill taunts for Seris sounds like "Hannah!, I... I am sorry."

But wasn't her sister's (= Seris's) name Abby? Since Furia is Sarah, according to her lore, Seris used to be Abby. So why Furia calls her Hannah? Or does this word have another meaning besides a name?

Somebody please clarify this moment to me, I'm not a native English speaker and may not know some things.
