Ash: And I won't die again. I'd promise.
Serena: ASH!!! NO!! DON'T!!
[The Dinobots and the Autobots make there way to USR]

[Tino gets in position, while Optimus and Lockdown fight. Then magic fires]

Starlight Glimmer: You see, you should have learned about your past, Tino! And you didn't know the truth about your real self!
[Optimus and Lockdown fight, then sees the group]
Optimus: TINO! ASH!
Starlight Glimmer: Just as you know... you're not really human, Tino. I know the truth about you and I know where you came from. And I know your real name.
[Optimus slides in, then shoots, and kills Starlight Glimmer]
[Lockdown takes Optimus buy surprise and traps him in a pillar with his sword]
