Considering that Capt. Jack is immortal, it's not such a big thing. However the title has a different context.
At the end of the Saturday photoshoot, Dreadnaught surprised all the Doctor Who cosplayers by blasting everyone with an high powered air spray. I happened to be in the middle of it so I played the running gag of Jack dying and reviving. Unbeknownst to me, when I revived, a Martha Jones cosplayer was about to reenact the scene from the episode Utopia where Jack and Martha meet, completely scaring the crap out of her a little too early. I also did the dying and reviving gag on Sunday with a gray Dalek named Simon.
Sadly, because of how spontaneous these events were, I haven't been able to find pics or vids of them. I'm still gonna be looking though.
