Are you sure he wasn't?
The Merlin told Harry that he (the Merlin) and a bunch of the most powerful WC members were preparing a counterstrike, to end the Red Court permanently.
Eb told Harry to come to the meeting to meet the rest of the gang preparing for a counterstrike to end the Red Court permanently.
Later, Eb and Vadderung and a bunch of unidentified powerful spellcasters show up and launch that "counterstrike" in response to Harry's information.
It seems very, very likely that the Merlin's overwhelming counterstrike plans and Eb's overwhelming counterstrike plans are one and the same. It would be really odd if the Merlin were planning that strike without including Eb, and they'd otherwise be drawing on a bunch of the same wizards like Rashid and Luccio and getting in each other's way.
Heck, Eb's opening line is: "The Merlin is preparing his counterstrike, and we're trying to find out how much they already know about it."
And when Harry doesn't show up for the meeting -- because he's unconscious with a broken back -- Eb says: "There are people in the Grey Council who think you aren't to be trusted. They're very, very wary of you."
That seems like a pretty clear reference to the Merlin.
