As a counter-argument against letting Harry speak - do we ship Lash and Harry? Because that's the vote that advances Lash route for Dresden.
Doesnt follow.
Trusting a person's word and assurances is as much a matter of knowing a person's history and their record as it is a matter of what you feel for them.
Lara Raith trusting Dresden's word, and vice versa, for example, is not based on any physical attraction that exists there either.
Any more than Marcone is.
In this case, Lash and Dresden have actually lived inside each other's head for two and a half years at this point.
She is still inside his head right now. He's almost definitely one of her Intimacies.
She can read him a hell of a lot better than she can read Molly, Infernal Exalt, which has implications for how reassuring he is.
We can certainly brute force this, but I dont think it would yield best results.
And given that its been his company and influence that brought her to a point where Molly could attempt to get things moving along without a lot more preptime? Having him play his hand might yield unexpected benefits.
Multiple social anchors are better than one for the purpose of stabilizing a person.
We shouldnt be looking to replace Dresden in her life, and more to supplement him.
