- If it took Vegeta and Nappa a year to get to earth, and Raditz got there early than perhaps the talk about finding “Goku” was a plan that was roughly 2 to 3 years before Vegeta arrived.
- There’s also the fact that the communicator devices can be spied upon, making it possible that Vegeta had plenty of time to plan his invasion and learn about earth.
- Not to mention when he took Capsule Corp’s ship to look for Goku and train. Making it possible that during that whole time he and Bulma were in contact. So when Vegeta returned to Earth it’s not that surprising that he listened to Bulma when she stated he needed a bath.
