So I got this idea in the middle of the night.
What if Summer Rose is reincarnated through
a similar processes like how Ozpin is with Oscar except it's Summer Rose with Adam Taurus.Summer try to convince Adam to help find Ozpin and Team RWBY and Adam try his hardest to ignore Summer but eventually gave in.
This happend because the God of Light want to expedite the process of defeating Salem and also to help Ozpin and Team RWBY.This happend after the end of volume 3.
If someone want to adopt this idea and write a story about it just do it.I give full permission just credit' me for the idea.
Also sorry for bad English.
