In "Severed Dreams," the dilemma faced by the Alexander in the teaser is
that if they jump, they'll end up leaving their fighters behind. A jump
engine rips the area open for that one ship, and closes it again right
behind it. What sometimes happens, as in "All Alone," is that *as a ship
comes out*, it releases its fighters. But you can't just follow a ship
into a jump point formed by another ship. You'd probably get torn apart
when space folded back on you, because the field opening the point is
primarily around the other ship.
