S2 had to change the bathroom extractor fan and CJ went to help. The only issue, was that the fan was in the attic and we had to cut the power to the house (and lights), so no one got a nasty shock while playing with the wiring.
Therefore, to go up into the attic S2 brought out the headtorches. And CJ was excellent with it, not removing or playing with it. In fact he loved wearing it so much, that after the fan was installed, he headed straight outside for some sliding in the dark!
