Just looking at the lap chart, I struggle to see at what point Vettel was 12th. And I believe he was behind Webber and Alonso after the Safety Car.
From my recollection Vettel came out in 12th after his first pitstopped which was a long time before everybody else's. IMO going to watch the race this evening as there is so much to take in trackside, but we were all very surprised when we saw him peel into the pits so early. It looked like his race was stuffed. The safety car got him right back up there. My recollection may fail me but this is how I remember it unfolding.
