Tired of Zenos (spoilers)

[Lauront]

True, but he never specifies how really, and it's contradicted by Zenos's own recollection, as he states it's a shame Elidibus just fled and he'd have enjoyed a fight against himself, or some such twaddle. Elidibus is powerful enough by that point to at least be able to go against the WoL who had already bested Zenos and his Shinryu form by that point, and who benefits from Hydaelyn's protection via the Blessing.

To suggest he wouldn't even register on Zenos's radar, while Gaius and Estinien would, requires suspension of disbelief, IMO. What does stand out is the fact that he's a primal, and Zenos has managed to take control of one before, and may well have given an indication that he could do so again if he so pleased. So I believe he overpowered him in that sense - with Zenos being a potential asset and with nothing to gain by then in fighting him, he took his leave.
