well at the beginning of summer vince went to new york (which is where his parents live) to visit and was there for about a month before his on and off ex called him up and told him he had a baby on the way, which was in about late may/early june so if you wanna say they had a fling in that time until he got the news and had to leave we could go with that? it could get dramatic, she could definitely hold some sort of grudge against him even if you'd like!
