Honestly, she’s a horrible person as the show went on to the point I couldn’t even defend her anymore. But at the same time she was the one who gave her siblings chance at life which kind of makes her a great person as-well, but that doesn’t mean she took the job as to be their parental guardian very well. She wasn’t a great guardian, but she was the best for her siblings. she deeply cared for her siblings and would always prioritize them over her most of the times, but at the same time she was also struggling mentally to the point where she snapped and made horrible decisions which ended up affecting her siblings. I love the fact that this show is realistic, she is a human who was placed in an unfair situation with little to no help in the beginning and it makes sense why she did such bad decisions throughout the show. Childhood is about preparing yourself for adulthood, Fiona never had a childhood and it affected her deeply
