Thanks!
I'm still trying to see how I can integrate my character into the story. It's so difficult when the story is far on its way already.
I can imagine, especially since a lot of characters are on a place other than campus.
Perhaps you can find a friend in the newer characters. There have to be groups of friends on this campus that we haven't heard about so far. So that would be a plausible entrance. Another could be that you have friends among the characters that have been around for a longer time. You could ask around with the other players who would be up for that. Then there might be a reason why your character was not involved in the daily business (so much) up till now. Remember that Greta also has a half-brother walking around, (plus a notorious NPC half-sister) whom she might know.
Furthermore, your character probably has had some of the PC's in her class. (check for the age I guess?) So even though Greta was perhaps not friends with these guy or gal, they might know each other by name, and at least by face.
Places to meet would be around campus, in classes or at the campus café (which unofficially goes by 'the Coffee Station')
And Dallas, ofcourse your character knows Dallas, because he hosts the parties. He might not know your character though.
Moreover, one way or another your character has heard (or will hear soon enough) about the murder on the headmaster.
Maybe there's someone who sends you the recording Dallas made.
What else? perhaps your room is next to one of the other characters? And you just run into them or have another excuse to talk to them.
So my suggestion would be: post your first post. Let Greta have her introduction. Ask other players if they want their characters to have a connection to her. Make a suggestion about what that could be.
Oh yeah.. and texting is a thing.
Hope that helps.
