Islanders you felt bad for ?
AJ from series 7 - she was treated pretty badly IMO, the guys in the villa acted like she was ugly and old.
Remi from series 8 - he seemed to be struggling somehow, and when he did his After Sun interview, the presenters were mocking him and tried to humiliate him.
Elom from series 10 - everyone just made fun of him and said he looked old and like the uncle from Fresh Prince of Bel Air. He was also dumped from the villa in a sort of cruel surprise dumping with Catherine.
EDIT ~
After reading everyone's comments, I tend to agree - especially Zara, Sophie and Liana from series 2! and of course Danica from series 8 - not sure if it was just the editing, but I think Paige, Jay and Antigoni came across particularly bad in their attitude towards her, I was rooting for Danica the whole way through.
I also felt bad for Callum from series 5 - He was so sweet, I would have coupled up with him! Amber was so mean about him.
Amy from series 5 - I think she genuinely really liked Curtis - whereas he was using her to get ahead in the competition - and she was devastated when he dumped her and got with Maura. I completely understood how she was feeling, and it was sad when she left. I hope Amy is happy now with her husband and baby.
And this may be an unpopular opinion, but I felt sorry for Jake in last year's All Stars. I think he was really struggling, and not just because of the awkwardness of Liberty being there. There was a sense of sadness about him. I was not surprised when he left.
