Vegeta/History

Vegeta makes an appearance with Goku and the others upon arriving to see Orion he reacts weirdly to her before being promptly hit on the head by Bulma. Vegeta makes another appearance at the party offscreen calling over Bulma, then at Android 16 and Orion's wedding. He also tried to get Orion to forgive Android 16 when he lied about her. 
He was in the car at the time when Orion was driving recklessly and decided to try and tell Android 16 of his involvement with Orion's mental state. Vegeta arrived with Orion, Goku, Trunks and Android 16 to Planet Vampa where they meet Broly and Paragus, he ends up arguing with Goku the entire time though.
