Re: Elphin safety
I had the pleasure of spending a few hours in a bar last December & giving some advice to Radagast The Brown on the subject of why his printers always gave him trouble after months away filming (Inkjets dried up) for printing off scripts etc on his return home & told him to go get a half decent laser (or even a crappy one).
I admit I got a kick out of telling The Doctor how to resolve his technical difficulties.
