We Know that Mab has the power and the opportunity to do so. But, if it wasn't Mab we'd have to ask who else coudl it have been?
If it was just LC, or Just Mouse alone it wouldn't be so significant.
If it was important enough in the Plot for Harry to have his memory if it tampered with about it, then it's no where near Null.
I'm gonna go with Tami on this.
LC is significant, it had a tarp over it which was quite similar to the tarp over Harry's thoughts about fire in small favor.
SOI would exist so she would have the opportunity to act as proxy for Mab.
Now, before I go any further I need to get familiar with debates at issue and probably reread books in question.
Significant questions though:
Did Harry ever use LC after White Knight?
Did Cowl's attack upon Harry corrupt LC in some capacity?
Was Shagnasty abduction of Thomas a prod for Harry to use LC?
Did the Outsider Faction want Harry to use LC?
Could Harry's use of a corrupted LC hurt/corrupt SOI?
Could Cowl have linked to LC via some thamaturgical spell?
