Pe-lead, first impression is SeTi. He has the fluid posture and rapid, almost jumpy movements of Pe-lead, as well as the eye-centricity (eyes leading the direction of his face). His eyes toggle in the linear manner of Se, back and forth without brushing the environment randomly, and he lifts his brow straight up (Ni) rather than slanting it upward toward the center (Si). His upper eyelids hang over his eyes consistently, giving him a sleepy look despite his active, lively energy. This is a sign of Ni, which makes me question if he isn't a Ni subtype. His articulation seems warm and intentional (Fe), and he appears to cool down (Ti) with all tension leaving his face when he stops to contemplate.
His 'toggling' seems more distant than Ne, and he does Ni 'wake-ups', if that's a thing, where it's like he's coming back to reality, more so than Ne togglers do. I find the T/F fucntions harder to spot in this sample, and his emotions seem to swell a bit, but I also hear quite a bit of nasalness to his voice, and asymmetry (see 8:30 in the second vid). At 15:25 in the second vid he does what looks like a big Fi smile. I'd lean to SeFi if I had to pick...
