This week's was very interesting. Ethan is clearly from our time...but I'm not sure Matt is!
Really nice to see Jenny, er Lucy, er Jenny again, that woman is gorgeous!
Ethan is clearly matt's Brother or uncle.
Remember in Stargate continuum, Mitchell had to go back and save the world, but the best wormhole available left him a decade to wank about with nothing to do waiting for the zero hour when he could save the world.
Matt's pappy is from the future, and to save the world he came back, but he was pretty sure he wouldn't live long enough to save the day so he made a kid. Explaining Ethan is either that he is Matts brother who disappeared or that it was Matt's grandpappy who was from the future who had two children, so it's Matt's father who was also made to make him to be ready for the final battle.
In the first episode Matt was correcting Connor on the visual senses of the dinosaur they were tracking. Connor was saying "you can't be sure, this is theoretical" but matt was sure about what he said and right about what he said because if he wasn't from the future then he certainly had the education of some one from the future.
