It's as plain as day... They are not hiding anything in the trailer. It's Vader's helmet when Luke says, "My father has it.."... It's Luke's hand on R2 when Luke says, "I have it..."... and it's Rey handing the lightsaber to Queen Leia when Luke says, "My sister has it...". The only possible question is, who is he…

It's Rey handing the saber to Leia...

I was thinking since he was within the planets atmosphere, only one was needed...
