Did Eric know about Dylan giving his website adress to Brooks? If so how did he react? If not how would have he reacted?

Eric didn’t know about it. Dylan made Brooks swear not to tell how he obtained the url. Eric would’ve been majorly upset and seen it as a betrayal of their friendship especially since he considered Brooks a top five enemy around that time period. If it didn’t damage Dylan and Eric’s friendship it certainly would’ve put a major riff into it. I don’t necessarily see that Eric would burn his bridges with Dylan..since Dylan was pretty much all he had… but Dylan would have had to eat crow to make it up if he couldn’t stand to lose Eric’s friendship. There of course would be trust issues for Eric. Dylan obviously knew the risk he ran informing Brooks of the crazy shit Eric was pulling on his website that ran the risk of putting his friend in potential danger.
