If Thomas touched a coin for example, I think it will be at least 10 times harder for him to block the influence. I mean, the demon is half of his soul. If the fallen promise the demon food which the demon virtually will agrees, technically the fallen already owned half of Thomas's soul in one shot.
Uriel and Michael would both disagree, as per their comments and disposition toward Harry during his time with Lasciel and the denouement of Ghost Story.
I am not worried about Lara wraith so much I am worried about Papa Wraith.
If one of those coins fall into old Papa Wraith...
If the fallen can help papa Wraith regain his sealed powers...
An ancient white vampire + full magic immunity + fallen angel powers is a very scary combination. In fact, it look like a perfect wizard slayer to me.
Interesting thought, but from what I understand, the current consensus is Papa Raith gets his immunity to enemy magic from HWWB. Deirdre's Denarian was on Team Nic, and wouldn't cooperate with the Walker. Opposing agenda.
I doubt it. The other houses' leadership are dead after WN.
From where we last saw her, Lara isn't in a great position. She could be persuaded to take more power.
Yes, the WN Deeps Battle devastated (not decimated) her opposition in the White Court, and let House Raith effectively take control. I imagine it will take the other houses decades or centuries to become contenders again. However, her House was wounded as well, and with Papa Raith (please make that a pizza joint) on a leash, the other houses were still somewhat beholden to her bidding. Their losses count as her losses in any conflict where the White Court would stand unified.
Also, remember Shagnasty. That Skinwalker waltzed right into Raith manor and made a field day out of ripping her personal guards apart in her very home. News of that demonstrates vulnerability, and news like that spreads. It also must have rattled her.
I don't believe she's been onscreen since Turn Coat (unless short stories - need to catch up on those), so I don't know how well the White Court is handling the Fomor. They mentioned something in Ghost Story with the Whamp at Murphy's but details escape me presently. I think they had their hands full, though.
Given these circumstances, I absolutely think Lara would like a power boost, for either the organization, herself, or both. She wouldn't like being at the mercy of a Fallen, but unlike Papa Raith, I don't see a conflict of interest in such an alliance. She could be persuaded, I think.
