In Dragon Ball Super episode 88, around 20:15 mark, Gohan said something to Piccolo about the idea to become more powerful.
In one subtitle, I've read Gohan asked Piccolo to do some attack or technique together. But in other translation, Gohan asked Piccolo to do a combined technique or a fusion together.
It's also raising speculation among fans too (YouTube video about Gohan's fusion with Piccolo)
Which one is true?
