There was a live chat with Jonathan on Facebook, and some interesting info on Lockwood and Co were in there! I'm going to link to each thread there related here:

Among the interesting bits of info here, some information on Holly Munro, and her ethnicity!

Awesome! But, goddammit, I headcannoned that Lucy's eyes were grey...

Well, on the bright side there probably is an AU somewhere where she does have grey eyes, lol

Yeah... I just thought if Lockwood had brown eyes and George had blue ones, she might as well have grey ones so all bases are covered.
