Irreplaceable

Peronas husband has died, leaving behind her and Zoro, their small son.
Out of options she moves in with Mihawk, the distant father of her late husband, after he suggests so.
Is it possible for them to move forward or has the loss been too much?

Slight sexual harassment, miss use of alcohol, domestic abuse. I'm trying to keep this as clean as possible, but I will tag this mature if needed.
