I know you asked for more details @Mactheknife
, but at the mo all I've got are parallels and first impressions (and tbh when typing celebs - that's all we got anyway, just dressed in different words coming from different people...):
The other guy in the above video (Sam Loeffler - his brother) looks a lot like an ILE guy I know.
From around 10:42 to 12:03 mins in you can see how Sam gets annoyed and Pete does too but it's different and he kind of tries to smooth things over a bit (Fi?).
You can see how they sit the same way in 13:30, probably both EP temperament.
And how there's faint Fe coming from Sam throughout the interview (he tries to make little jokes here and there, little laughs that I've seen commented on as signs of Fe-HA before) and Pete comes across as a "serious" quadra type in comparison. These guys don't seem to be Fe-egos (at least not if judging from this vid).
So for Pete that'd be EP + Fi in ego -> NeFi or SeFi
I didn't see any Se in this guy so far (Se egos tend to have a bit of tension in them, in their body, even the e7s) and there was a sign of Ne in the "Fallon-voice". -> NeFi
He has this calm presence and doesn't show much Ne and that just makes me go -> IEE-Fi > IEE-Ne for him
First impressions though, so pls take it with a scoop of salt.
