Read the whole thing, cause I had a Lyft ride and waiting for a train and a train ride, and so had time to kill.
It's, uh, maybe not worth it? Not that I expected much, but the Nick stuff is probably what's most distinctly important (which makes sense given what the document is). The deposition is largely just drilling down on the fact that he really, really has no reason to say that the defendants - both the individuals and Funimaton - were responsible for the impact to his reputation. A lot of reviewing of the numerous articles published about this which were unrelated to their comments, of the numerous conventions that canceled him without any input from the defendants, etc.
EDIT: Rather- that in itself is pretty important because it shows there's, like, 0 reason to even go after the defendants! But don't expect many individually interesting moments beyond the Nick and fan club stuff.
