Oh, I see what you were asking now. Can the ring bearer move through other models while wearing the ring. In that case, your opponent would be correct if there were not an FAQ that added the required line about the ring bearer being able to move through other models. However, just such an FAQ exists adding that line so you are in the clear.
I'll add a link to the post to make it quick to find the next time the matter comes up for anyone. The pg. 90 alteration.
