RHYSAND AND FEYRE POV Feyre was injured after the first attempt and didn't even begin to solve the riddle of Amarnatha to free Tamlin....HER Tamlin. She had to win two more attempts and solve the riddle

then Rhysand entered the cell followed by the girl he was sitting next to while watching the rehearsal, During rehearsals, Rhysand covered the girl's eyes so she wouldn't look. , she was probably his girlfriend or something like that

Rhysand enters the cell with his partner, keeps a bit in front of her, he doesn't quite trust Feyra, who of course doesn't stand a chance against them, but he's a human being, and people are young and stupid, which equals that they're hasty

Rhysand: "don't panic too much, we really want to help you...you know, so that you live to see another attempt"

Feyre knows she shouldn't trust Rhysand because he was one of the reasons she was in this bad situation, on the other hand this girl seemed friendly and clearly didn't like the sight of blood....she could be Feyre's only potential ally under that damn mountain
