1. In Turn Coat Listen to Winds mentions to Shagnasty that Harry nearly beat him without knowing the Dine yet alone the Old Ways. What other Old Ways was he referring to, since the Dine aka the Blessing Way seems to qualify as tradition in the oldest sense.
2. What did Listen to Winds and Ancient Mai do while the others were busy fighting the Grey Men? It did not seem like they accomplished anything notwithstanding the thrashing Listen to Winds gave to Shagnasty.
1) Well addressed already.
2) My guess is Mai and LTW did something on the order of what the fetch (we assume) did to slow Harry down in the second attack at the hotel in Proven Guilty. Threw up a kind of ward that slowed their progress, didnt actually damage or stop them. It would be something akin to make them feel like they were running through waist deep water, making it harder to move quickly and make them more exhausted by the time they reached the fight.
The bigger outstanding question is that Harry mentions that there were two summoners holding the gate open for the spiders. They leave well before anyone could get a look at them, which is what Eb is angry at Harry at for not investigating while he could instead of saving Thomas. One, of course, was Peabody. I have always assumed the other was Cowl, but it is not a proven fact. But it would, potentially, at least somewhat exonerate Mai and LTW from being there in that capacity. Assuming the other one WAS someone on the senior council (I think Harry believes that to be true) it leaves the Gatekeeper, Langtry, or Martha Liberty. Cirstos wasnt appointed yet but I guess it could have been him. I agree with Eb so far though, I think Cristos is just stupid not evil.
Or, of course, in the common parlance of these forums: OMG TIME TRAVEL HI-JINKS!!1!one
