He is going to be so crushed!
When his sister died he lost his leg and couldn't swim, which is what he loved.
And he blamed his other sister. So she left and he was struggling emotionally. Fawn helped him through it and he grew to love her.
When he was captured, he became a 'man' and wanted to get ba K to RiverClan to tell Fawn he loves her and wants to be mates.....
But- she died XD
