I parsed through all my dynastynet logs and Lun was on a few times to dispense his wisdom in some Q&A stuff, but most of it wasn't way-plot related. In fact he explicitly asks for no plot-related questions. There's some stuff about inspiration and whatnot, but not about plot points. But god is it weird seing Exiled, Excell,Iteroth, and all those guys in those logs.
In terms of actual Lun quotes about theories:
[16:30] <LunC> It's fun to see what people come up with
[16:30] <LunC> I highly encourage theorizing
This is from the
Episode 6 release party log which is probably the Q&A you're thinking of. There's a lot of good stuff in there, but it's a LOT of text. There were over 70-some people in there and we each gave them a turn to talk to Lun, eventually devolving into craziness.
