*;lasldfk is never not skeevy*
On the Disc, beings with human forms tended to pick up human characteristics. That must be the case here as well, at least to some extent, because here was Robin, as real as the Hogfather, or the Sandman (or himself). For whatever amount of sense that made, it was... comforting? Fascinating. And generally really cool. Lobsang hadn't thought the same rules would still be in play (beyond things like "Up things come down"), so he was a little surprised. Surprised but pleased.
"Probably because it's a time machine." Lobsang replied very seriously. "I'm not from this universe (in fact, haven't I seen you over the system?) and I think maybe it reacted to... to that." Caution. Fascinating was not the same as safe. As it was written (somewhere, supposedly), 'I was not born -- yesterday'. So: caution.
"I used to make clocks and things back at home. Maybe the dimensional rips thought I should come here, instead."
