I was referring to the scene early in the episode when Nimira was talking to Tuvok mind to mind without a meld and without touching. What left me scratching my head was the brief mind to mind conversation when Nimira basically asked Tuvok why he insists on talking vocally instead of with his mind (again, no hands), and Tuvok acted like casually "mind talking" like that was old hat, he just didn't do it with limited humans. They were just walking along, not touching, just having a chat in their minds. So, basically that means Vulcans can talk to Betazoid-like aliens non-vocally and without a mind meld. I hadn't seen evidence of this in previous Trek...IIRC. Unless my mind is fuzzy on this, which is very possible.
