If Kalista had to choose between Gangplank and MF...
Who would she choose?
betrayed her and her parents by refusing to pay and killing those he entrusted with a service
BUT
was a major player in Bilgewater, and as such she served Gangplank. She stabbed him in the back when he expected it the least, and her actions led to chaos and attracted much anger.
So if the Spirit of Vengeance
found herself summoned by both Sarah and Vincent (I assume its his name, because of his father - if that's still canon), who would she choose?
