JULIETTE - Possible acquaintance, friendly annoyance... Not sure whether they'd know each other, but Juliette is perpetually interested in the Department of Mysteries (and it currently trying-- and failing-- to get Landis to divulge info on his experience working there). So perhaps if they cross paths she might poke him a bit about his career. Also, she worked briefly with Johann and remains on good terms with him. I could see them all sharing an awkward drink or something. Not sure how she'd feel about a muggleborn werewolf if she were to know that's what he is. (Though vampires the like fascinate her for their... er... magical properties.) She is not so put off as some people are when it comes to dead things. She works with a lot of weird ingredients. But she'd probably think that Colin needs to get out more. This could be fun/funny.

MOLLY - Might have crossed paths in school. They're around the same age. She doesn't look down on people with weird interests, but his intelligence might overwhelm her/make her nervous, so I don't know about these two. In any case, Molly is not really the enemy-making sort, so perhaps they just know each other as neutral acquaintances. Her brother Frank is a recently-converted direwolf, so Molly might become more invested in werewolf rights in the near future. They could become friends after that if they aren't already sorta-opposite-ish-in-several-ways friends.

Juliette - Would be up for that! Colin's trying to get Johann to get out more, so that could be rather amusingly awkward. However, Colin's out of commission for a bit, so the earliest I can see this is...May? (He's chained up in Dugan's apartment and being held by teh WBA for a few weeks). He'd certainly spill his secrets to her if she showed interest in his work, haha. And also because she's hot

Molly - I could see them being friendly, though Colin would be a little dismissive if she doesn't follow him on intellectual matters. He's supportive to new werewolves, though, so he would want to help her with Frank if she needed it, even if they're just acquaintances.

::Flannery::
Oh look! A fellow Unspeakable! Flannery works in the Potion & Herbological Research Office and is still in training. Boo! But her responsibilities are starting to become more and more massive so it can be said that her time as a trainee is starting to come to an end! Woo! Anywho, I could see Colin and Flannery being friends of some sort? She wouldn't find his talk of death and whatnot all that weird. They're Unspeakables for goodness sake! Just.. no having dibs on her brain, mmkay?

 I think when she started with the DOM in 2005, he made her uncomfortable, but after he was bitten she began to feel sorry for him and since he has come back she has been trying to be more open minded. I think she might have even grown fond of him. Anyway she has a deep respect for him and all of her colleagues, so maybe an office friendship?
