I don't think he is ESFj or ISFp. He seems like a typical ENFp to be honest. He is even nailed the ExFp look from a VI point of view. And oh, all the tripping and meds jokes? Totally IEE. Remind me of that time where I went to a Lady Gaga concert with an IEE friend and lo and behold, it's like an IEE meeting. I swear it was like every IEE teenager in the planet was there doing their usual business, being zany and drunk.
