"... play that event again." Does this mean I must have a second copy of it in my hand, and it is that second copy that gets removed from the game?

No you use the copy you just played

If I'm not wrong, playing an event on someone bearing this tattoo means that if the event is canceled, It can still be played a second time, as a card is played even if it's effects are canceled.
