Merlin is Summer’s best friend in Camelot. She doesn’t know if she would even still be there without him. Even though he doesn’t reciprocate her desire for him, she’s decided she doesn’t care — she wouldn’t give up his friendship for anything. She would rather be friends with him, if that’s what she can have, than walk away.

(But if the chance ever came for something else, she wouldn’t turn it down … )
