[Star Trek] The effect of falling through a warp bubble

So the easiest analogy for the question is what would happen if someone were to jump off the Starship Enterprise while it was traveling at warp speed.

I would assume that within the warp field, bubble, whatever, would be essentially the same as in normal space but as the unfortunate soul passed through the edge of the field his atoms would essentially spread behind the ship like a comet tail. Sort of akin to falling into a black hole.

But then I wonder, if space is frictionless, would the person then simply continue to travel along with the ship at warp free floating within the warp field?

If you were in a space suit on the outside of the ship while it's at warp, you'd be fine as long as you didn't exit the warp bubble. Ships are tractor-beamed-towed through warp all the time using the same principle. 

But yeah, falling through the warp bubble probably isn't a good idea. With the right equipment it IS survivable though. Photon torpedos have "warp sustainers" built into them so that they can continue at warp-speed for a few minutes after being launched from warp, making warp-to-warp combat possible. The saucer section also has warp sustainers, to allow it an ability to escape if separated during warp.

Warp sustainers cannot _create_ a warp field, but they can keep a pre-existing one going for a few minutes.
