no. this takes multiple episodes over multiple seasons to explain everything but here is what happened to jeff
when he discovered roger was an alien stan said to protect the family either jeff or roger would have to die. but roger said that he would leave the planet and then both could live. but when the tractor beam came to pick up roger he threw jeff in instead sending jeff into outer space. jeff eventually escaped and stole an escape pod and tried to make his way back to earth. eventually it seemed like he did but it turned out to be an alien disguised as jeff. the real jeff had been dissected and killed. but they upload his brain into the alien copies body but dont tell him he is now an alien. when jeff and haylee decide they want to have kids roger reveals that jeff has an alien body and so they cant cross breed so it impossible for them to have babies. but roger could eat jeffs brain which would make him man pregnant and then he could give birth to jeff back in a human body. and thats exactly what happened. so jeff knows roger is an alien now
