Re: Kakashi Knew About Mangekyou?
I'm disregarding the ''planning on killing Gai'' part because it's utter and complete hogwash, but you had me going for a moment when you said that Kakashi was able to unlock his MS because Obito did.

But here's the problem.
It's clear that Obito's been using his version of Kamui (which is a MS technique) for his intangibility.
The thing is, he used it against Minato, way back during the Kyuubi attack.
Kakashi was still a teen back then and he didn't have any MS powers. He clearly states that he's got something cool, a new jutsu to show Naruto just after the three year time leap and the first time he uses Kamui is during their pursuit of Gaara. Meaning that he managed to awaken his MS during the timeskip, not anytime before.
We still don't know how it works. If we believe that Kakashi actually did kill Rin or cause her death, why couldn't he awaken his MS back then?
Maybe it's different because he's a non Uchiha, maybe he had to come to terms with it. Maybe Kishi didn't think about it back then and decided to go with the MS/EMS/Rinnegan plot way after he started the manga (which is fairly certain).
Anyways, the only thing we are certain of is that Kakashi did not awaken his MS because his eye was connected to Obito's. Otherwise he would have been able to do it long ago.
