Something I've been wondering about. Earlier in the season when Magic was talking about his experience when Sam leaped into him, he talks about feeling another presence trying to "step in" so to speak which he apparently consented to. Which at the time, it was pointed out that in the original show there were those Sam leaped into who weren't likely to have consented to have him occupy their bodies, like Lee Harvey Oswald. But, in this episode we have Martinez leap into Magic. Did Magic also consent to becoming Martinez's host? Even if we consider the various people throughout the shows can sense the benevolent intent of Sam or Ben, which motivates them to consent to the leap, Martinez almost certainly wouldn't have had that. Does Martinez just go ahead and forcefully leap into his hosts? Is the "consent" just some rationalization Magic came up with after his experience with Sam? Or is this just another of the many inconsistencies with leaping that pop up on both shows?
Maybe it's not that a leaper needs consent to enter, so much that Sam wasn't the type to force his way in, while Martinez was.
As for why someone like Oswald or others would have granted consent... well, for one thing, they didn't really consciously know what they were being asked to do, but just felt a benevolent presence inviting them to step back for a while. I imagine that a lot of people in stressful situations, like the kind that Sam or Ben usually leap into, would find that an inviting offer.
And yes, it's an inconsistency, but it's a change for the better, since we have more sensitivity about bodily consent today, and the leaping process raises some uncomfortable questions without it.
