User blog comment:Bob the Wikipedian/The Verrat, the Reapers, and the Grimms/@comment-144.160.226.53-20120428192632

LCD on the points above:

The Reaper's ear was cut off - Some Wesen can regenerate

"The Reaper's ear arrived in a box, and was accompanied by a voice on the phone checking to see it arrived" - Not an issue, see above

"The voice on the phone seemed to indicate it was a representative of the Verrat" and "The Grimms have been assisting the Verrat as of late" - Not all Grimms as I doubt Nick's Aunt was
