Grace in book three made sense

She was never a character I expected to get redeemed but I'm glad she was. It actually felt believable too. I can see her not wanting to be destructive in front of Hazel because she doesn't want to turn her away from the apex. I can also see her telling Simon to play along in that octopus ballroom car, she's played by the train's rules before to advance her goals. She actually played the carnival games in the Lucky Cat Car so she could win the exit. I can also believe that Grace was genuinely touched by this kid and wanted to protect her from harm.
