Have you become trapped?

The other day we were using the hict trick to close a mass crit wormhole. For those of you unfamiliar with the hict trick, it allows you to close mass crit wormholes in relative safety. Hictor bubbles reduce the mass of your ship by 80% and stack, so with 3 of them, the mass of a cruiser comes down to less than that of a frig. The chances of your hictor getting stuck are very low (but still possibru). Sometimes it takes a few roundtrips to close the WH, but during this time it is unusual for anyone else to enter, as only the n00biest or most desperate of pilots will roll the dice on a mass crit WH.

This is the difference between a hict with a
100mn prop and a hict with 3 bubbles on it

So while I'm sitting on this WH with the hict waiting for the polarity timer to run out, I hear an activation. I had a few crewmembers on grid with me on the off chance that someone came through, and they all said "Activation?" on comms in a confused tone, not sure if I had gone back through, as my bubble wasn't up. We then watched in shock as the womhole disappeared, trapping the retard who had just come through into our wormhole. As it finally sank in that it wasn't any of us, I hit the bubble and then a wild tengu appeared on grid.

I shouted at the crew to get scram on him, as scouty t3s often fit nullifiers that allow them to ignore bubbles. My wingmen opened fire, we made short work of the tengu, and then his sad pod as well. Examination of the killmail revealed the first blaster-fit tengu I had ever seen. While there has always been a hybrid subsystem for the tengu, I hadn't actually seen one with it before in w-space. It was an unorthodox choice and made him completely useless when Jarek decloaked in the pilgrim and neuted him out. He also had a scanning sub on the ship but no probes or probe launcher, which raises the question of why he would risk entering a mass crit wormhole to begin with. At the very least he could have put the launcher, probes, and a mobile depot in cargo in case he ever found himself trapped. But no, his cargo held only ammo, not even paste or boosters, despite the tengu clearly being fit for pvp. At least the ship was cheap, despite a couple of faction mods (that were miraculously not destroyed).

Tl;dr: Always have friends on grid when you're closing a WH - you never know what the EVE gods will drop in your lap.
