Why would my ex boyfriend send a friend request to my sister on Facebook?

Anonymous

I broke up with him a week ago and I ended up blocking him due to him taking digs at me through posts on his wall and trying to hurt me and make me jealous with those posts.

A week later and he just sent my sister a friend request, seems weird when we are not together anymore and I've blocked him both on Facebook and Messenger. He never attempted to friend request her the past 10 months we have been together, so why now and extra strange he has only ever met her once and that was like 8 mths ago.

She blocked him straight away.

What do you think he was up to?
