Solten picks up on some of the subtext from Sadie's outburst. However, given his relatively low psyche (low rank amber), the confusion of the newfound relationship, and the constant onslaught of completely new things, he finds himself dragged along for a bit figuratively after recovering physically and following her away.
During the shadowwalk, he watches her closely, attempting to unravel some of the mystery of the emotional swings. As he misses most of the high level shifting of the shadow aspects, there's not a lot else to focus on anyway.
He catches Sadie when she stumbles back and inquires telepathically if she's alright (The typical relatively pointless and obvious question, but more intended to open a link and show concern). Out loud he says "Perhaps we should break here for a bit and exercise our mouths again. This whole walk was about speech, after all. Sadie, you've developed a bit of an accent, interesting."
((What kind of accent is it? I'm picturing either a small lisp-type thing due to the unfamiliar muscle no longer having magical assistence, or a New York City accent
