POINT 1
It seemed as if Bejiita would always have it in for Kakarotto. But he does warm to him; slowly. After all there's a very thin line between love and hate :>

In the end of movie 12 for example Bejiita actually apologizes for botching the fusion dance. He and Gokuu say each others name so softly. Then, he actually smiles at Gokuu *gasp* Not a sly smirk but a really sweet smile before he leaves :D awwwwww Gokuu even seemed kinda sad to see him go.

"Bejiita...we will meet again ..."

POINT 2
Bejiita becomes so obsessed with Gokuu I think to the point of stalking. In movie 6 the Namekusei-jins sent a distress call to earth. So Gokuu, Pikkoro, Gohan and Kuririn went to investigate. When they arrive the rest if the Z-warriors go and fight the robots while Gokuu takes care of Metaru Kuuraa. But just as Kuuraa got the upper hand out of no where Bejiita comes to the rescue. How did he even know where he was? Considering he was on another planet and no one told him what was going on at Namek.

POINT 3
It was the same in movie 12. Janenba was causing trouble in hell and Gokuu and Paikuhan were asked to check it out. Again just as Janeneba was winning Bejiita flies in through a plot hole and saves him. How does he always manage to know where he is? Does he have some sort of homing device on Gokuu that goes off when he's in trouble? And if he really hates him as much as he says, wouldn't he try to avoid him as much as possible?

POINT 4
Almost all of movie 12 was dubious now that I think of it. Again, there is a lot of unecessary contact. Bejiita's usually so touchy, but after a point he doesn't push Gokuu away anymore. They actually look kind of intimate in that one scene in the spike forest. At one point Gokuu "accidently" taps Bejiita on the bum. The look on his face was so funny when he "realized" where his hand was.

POINT 5
Movie 6 was no exception. Half the movie seemed to consist of Bejiita getting hurt or thrown back and Gokuu saving, touching or holding him in some way.
