Boyfriend of 7 months flying out of town to meet with his ex girlfriends brother?

Boyfriend booked a trip for a few days to spend time with a friend. I casually asked how they met since he lives across the country. He says they used to be roommates.

I noticed a friend suggestion on fb and noticed the friend he's going to see had the same last name as his ex. Turns out, his friend is his ex girlfriend's brother.

I think it's a tad dishonest he didn't tell me, but maybe he doesn't see the guy as his ex gfs brother?

More backstory: They broke up 2 years ago and a few weeks ago she called him and said nasty things about me (we don't know each other, so she just said a bunch of prejudiced things). One of his friends overheard the conversation and told me about it.

A few weeks later, he's flying to meet up with her brother (i dont think these things are related). She will not be there. He's not going to see her. She lives in another state and won't be there when he's there. I'm sure of that.

Just looking for different perspectives. It's not the end of the world, it just puts a bad taste I'm my mouth.
