Need gives the impression that she's snorted. (Is it a bad sign that she has this, but not smiling?) :Your faith in me astounds. I can't just ram a permanent change that large through without even telling you first.: That sentence is carrying a lot of weight in Mindspeech. She is actually kind of offended at the implication that she'd alter Raistlin's - anyone's - body that severely, even if it's an objective improvement, without even a discussion. Healing doesn't count. ...She technically can make those kinds of changes without permission, it's just a disgusting idea. Besides, her own ability to cause major permanent reshaping is limited enough that it takes a lot of incremental changes over time, a lot of power, or both.

Need smooths out her emotional state back into clearer focus and assumes a more tactical role. :I'll show you what I did later. Don't fall too far behind, either. Either slow down or speed up, don't get trampled by the horse coming through in five... four...:

She'll just be giving Raistlin directions and warnings like that to dodge trouble and avoid being spotted by anything nasty on their way north. There'll probably be a close one with the Sisters, who Need can only sense via the blankness of their total shielding, but altogether this would have been a good, clean escape if they didn't end up randomly teleported apart. With the termination of contact, her spell will last about five minutes more.
