After killing himself in the past and reading the book of time travel he finishes a device for travel.
Bruce: Finally done, now to test this watch and maybe try out the dimension traveling watch.
Then after trying out his new watch he try's his dimension watch.
Later he is in The RWBY universe.
Bruce: Yes it worked now I can travel in time and screw things AND travel to alternate dimensions and screw things up their. Anyways what exactly am I supposed to be doing again.
Suddenly Yang came by chasing after someone.
Bruce: Probably nothing I'll just wait until I get a real series.
And then he disappeared.
