Vegeta had joked to himself about Yondu acting like Piccolo and having an ability to collect children, having finally met up with Kyoko during this all with the anchoring, so adding another to the list, even if from another universe, causes that eyebrow of Vegeta's to raise higher, silently considering if to say something about it. Then doing so. He's too tired to really care right now. "Your collection of children keeps growing."

"I see." He adds regarding T'Challa being on the train. It seemed like both a good and bad thing; being here to have time with Yondu, but also being away from his universe. Especially if he's a hero as Yondu says he is. However, "I hope you're not expecting some sage advise from me about it all." You've seen what he was like, Yondu, was that really a man who gave a damn about 'getting to know' his own son from the future? Or even his current toddler son of that time?
