It does, but Thelim wasn't into it. She can guess what Yfandes might mean, though; she isn't just trying to transmit or trying to receive, like reaching out a hand or taking a hand; she's trying to respond, like in dancing where you would pay attention to someone else's whole body and let your own body shift instinctively in response to maintain a balance. The Gift of Mindspeech is, obviously, handling a very great deal that Thellim would not know how to handle consciously, in terms of sending a thought or receiving it. If Thellim can succeed at this subproblem in an unreasonably speed by the standards of this world, it won't be due to her conscious knowledge of how brains work - she didn't use that to Mindspeak in the first place - but because Thellim has a better idea of what her Gift would be trying to make her do, and better training in how to get out of the way of herself when her intuitions are trying to move her.
Thellim focuses on Melody, leans in closer, readies herself to pay attention to tiny cues from that 'direction' and respond to them, consciously gives herself permission for her sensory modalities to load strange information, and tries to flow along / get out of the way of whatever her Gift knows how to do.
She won't be too embarrassed if this doesn't work on the first try.
