So it turns out Vegeta does turn blue and Goku lets him finish Frieza off, you know I guess because it was the right for him to do it, so he does but just when w he was about to kill him( by this time Frieza was already defeats and lost his form because of Vegeta) one ups Vegeta and blows up the earth. Whis only managed to save Rochi, Krillin, Goku, Picollo, Gohan and I think was Vegetas daughter? Or bulla not sure. So Whis tells Goku he can turn back time by 3 minutes so he can go an kill Frieza quickly and he does with the kamejameha, Vegeta moves out of te way and Frieza dies. Vegeta doesn't know what happened because he thought he was gonna kill Froeza but Bulma Or bula tell him Goku saved him and the earth, so in the end Goku tells Vegeta that they should work together more often like Whis told them and none of that would have happened, Vegeta does say "we did see eye to eye today" and Goku laughs and Fin.
So what do you think? Excuse me if there's spelling erros or whatever, the autocorrect in my phone is a drag ._. Oh and btw I saw this on facebook but I can't put the video here but I'm aure of you look for it like right now you can still find it.
