Common theory is that Eb mind-whammied Thomas into the clumsy attempt on Etri's life as part of some scheme to get Harry to "return" to the Council, and that this is why the corner hounds show up later- Eb has just time traveled.
Proposing a variant: The Ebenezer we see at the beginning of Peace Talks is the Future Eb- time traveling not to whammy Thomas but to give himself an alibi after running into Harry at Thomas's apartment. Hence making a stink which a) Proved Etri was home and b) Provided lots of witnesses his own hands were clean.
His angry freakout over Maggie being there takes on a new dimension in that case- changes how the scene reads.
Thought I'd share.
