I heard a rumor that...

Yusuke and Jin were half brothers...Is this true?I mean I haven't seen the tampil since I was little and I'm membaca the komik jepang now and re-watching but I'm only on season one....Here's what I read

Apparently there is an exchange of dialog in the series that lead some people to believe that Jin and Yusuke are half-brothers. This dialog occurs in Episode 40: "Jin the WindMaster", when Kuwabara is saying how Yusuke rarely connects with anyone, and how that the only one who can really talk to him is Keiko.

Kuwabara: "But this Jin guy's just the same, like a twin."
Botan: "Well, that will make fighting against him difficult."
Kurama: (chuckles weakly)
Botan: "What's wrong Kurama? Are anda alright?"
Kurama: "Just laughing. It seems anda don't know brothers very well, Botan."
