I noticed she was looking straight down - Ti. Her body seemed to move as a whole - P-lead. Casual hands - P-lead. Pressing thumb and forefinger together - Ti. Some head nods (with rest of body moving) - Je. Buoyant undercurrent - Ne. Blinking while remembering specifics - Si.
She doesn't seem to have the inertial energy of a Pi lead. I think she's a Pe lead then. The Pe lead who uses Ne/Si and Ti is an NeTi. I guess her Je was Fe. I ought to rewatch the video with that in mind.
Really? Why Je-lead? i.imgur.com/AXODpNc.gif In this first gif I thought she was eye-centered. As her eyes do something, the rest of the body quickly follows. Her torso is also swaying with her head without any rigidity.
