Doing a friend a favor...

I saw the same, SeFi. I could actually somehow hear that he was probably Pe from when he was just talking to you in your video, not a real "sign" but as a Se lead myself, engaged to an Se lead, I feel like I have radar for it. But he is steered by his eyes, where they look his head must go. He perpetually loosely sways, even though he is firmly leaned back, as Pe leads do, we can't help it and it's entirely non-intentional. He has the momentum, the exciting energy.

So, judgement functions seemed clear, he snarls asymmetrically while speaking quite a bit, so Fi is in there. Perception functions, there wasn't as much for me to go on, but his eyes were steady and didn't blink much. His gaze did not come across as gentle, or naive, and I didn't catch any loose fluttering across surfaces. Plus he doesn't really have the "floaty" feeling I get from Ne leads, he feels much more focused rather than someone with a "christmas tree light" pattern going off in his brain if that makes sense.
