I wonder why Thomas has never said anything about his soulgaze with Harry? Thomas; assuming he someday gets released from Demonreach, and Molly, are the only two living characters I could have a conversation about what they each saw when they shared a soulgaze with Harry. At one time I would have said there was a fair possibility this could happen, but even when Thomas gets back in the world, with Molly often gone and maybe becoming a bit less human; and possible obligations she might have to the Winter Knight, it might be something she wouldn't feel or be able to openly talk about any longer.
If Thomas became a KoTC, maybe he and Michael could share what they each saw when they gazed at Harry's soul, though I have a feeling Michael might feel it would be rude to openly discuss such a topic without Harry's explicit permission.
Here's an interesting related question. Damn, it needs it's own thread. Look for my next new thread.
