Puzzled at how starscream used his clone to cheat autobots. Did starscream used some time-warp trick to cheat autobots and broke into bot-base? Why Optimus told Arcee to close the ground-bridge so that SS left the bot-base with 3 keys? When SS was teleported back to the spot where his clone was, the autobots movements were very slow (time warp I think), but he plunged into another portal which Optimus was not quick enough to follow into. How did SS got the second portal?
