I think that part of track closest to the picture is not part of the sea serpent roll which has its dive loop further along into the area dug out, that part of track closest thats up is actually for the other dive loop.
Are you serious? That's obliviously the Sea Serpent roll. Knowing it lays in the elevated trench and knowing form the aerial updates that lays directly in a line with the Cobra roll entrance, not even talking about the half corkscrew radius going directly at it.
Can't wait for a full circuit of the ride. I suspect them to finish of the Sea Serpent going over to the first drop (from the point just prior to going under the sea serpent) into the Dive loop continuing to the other Dive loop make the first airtime hill and after that the second. Then they work on the hill on the first drop form inversion to sea serpent, going on the the vertical lift then the last turn into the brakes and finally the first lift. prediction not fiction.
