Kind of a pity Rhys can't go through, although he makes a good point, if everyone could get through it would be chaos. Does make me wonder who the little London boy was in an earlier chapter though, since he could walk through.

Hope it won't take Rhys long to print out a few white fivers so Ianto can get on with buying what he needs, but maybe he'd better check that he can bring things through from the past before he buys anything else!
