Do It At Least For Charles

Grace was conflicted and didn't know what to do or say. Already it was a huge sacrifice to let go of the love of her life for another woman. 

And now, hearing how Jace painted their love and how impossible he made her believe, it was for him to let go, she found her resolve crumbling like a pack of cards. Could she be so heartless as Jace made it look like to continue to say no? 

As if he hadn't convinced her enough, Jace continued,

"If not for anything, think of Charles. You know he has trust issues. Marianna might be his birth mother, but you're the only woman apart from my mother that he loves and can relate with freely."

"How do you think this whole thing will affect him? Think about all the sacrifices you made and the effort you've put in to bring him up to the point he is now? Do you want all that to go down the drain by handing him over to a total stranger… because that is what Marianna is to him as we speak."
