Being as unprepared for the sudden (and absolutely unforseen) change of events, Robin didn't do a roll to soften the impact he had on the ground. Something like that wasn't in his muscle memory, as his last mandatory judo session was over a decade ago. His legs gave way when they met the concrete slabs with a disturbing chrunching sound, he lost the feeling in his legs and dropped on his back. "Uuuuuurgh." was the only sound that he could make after this glorious jump. It would take him some moments to collect himself, and for the pain to subside. But when he eventually saw his surrounding again, and not the hot-white stars of pain, he says "Verdammter Scheiß... argh, well... let us note that this place is not like my normal dreams. It seems that I can't control anything here."
