Jim
You had to work on an article for the Gotham Gazette and you needed Jim as a source.
Bruce
Your dad worked for Wayne Enterprises and you went to one of the events.
Alfred
You worked at the G.C.P.D. as the new Forensic Analysist and you caught his attention because you were so smart.
Jerome
You were one of his cult members and he made you his assistant after he met you. What can he say, you had him from hello. ;)
Edward
You just happened to be at the Sirens club when he walked in. He was too nervous to talk to you for a while, until Barbara basically started a conversation for him.
