So while Toby's compass is also set to good, it varies between human!Good and Faerie!Good, which seems pretty different from Angel!good... Also she thinks the angels are all complete nutters, so that might count as a grudge? Also Cas in particular she's had that whole 'you are completely mad for not being scared of magic backlash/DEATH so you must be an idiot' conversation...

But she could also be persuaded to work with him. idk if it's enough of a grudge, but there are some people she just doesn't like...
