On the other hand, how much can he change without changing WHO Elves are talking with?
Even best case scenario: MC doesn't get involved with Cuntemplars, Elves like him, majority of humans entering Neverwhere (and controlling who goes there) are Templars.
And what are they like? Controlling, deceptive, lying bastards.
As much as it pains me, MC might be forced to change the order from inside to ensure stuff doesn't get even worse.
The mere thought of working with the order and Kaija makes me sick...
