Gai/Lee , what is the link?Brothers?

[davidou]

when i was reading this chap i was like, eithe lee is gai's son or kishi made a mistake not making him his son. it makes no sense how similar they are, they both suck at ninjutsu and genjutsu. the booth look the same besides the shape of their eyes. they are almost copies of each other there has to be some relation.

You forgot about Dai , those 3 are the same!
Those 3 have to share a part of the same blood.

I won't understand Gai ( as Lee's father ) playing the role of Lee's father without telling him that he actually is his father.

I would understand that Gai ( as Lee's brother ) didn't find the moment to say :"Lee , I'm your brother , your father is dead to save me and I took care of you"
