During the level 99 Dawntrail main story quest "A Comforting Hand", if you talk to Melancholy outside of the Backroom, she says:
"I was scared out of my wits when the machines started attacking, and I'm still shaking... But seeing you makes me feel a better. Thanks for coming by."
Feel a better doesn't make sense, and should either be "feel better" or something like "feel a bit better".
