It's a drastically different experience to get in that caravan as a human after playing a dwarf for so long.
I do remember you having an elf that went back and forth from the Mist Camp, while I scarcely remember Markus leaving Barovia. You, being the player of Markus, know better than I how often he's been in the caravan, but I think the drastic difference you're noticing is that the carvan was lighter on Sister Rose than it was on Markus.
