Tbf you don't associate a cute boy she met with the Greek godlike figures that is Apeiron.
Just proves that Joe is as good at unconsciously Clark Kenting as he is with everything else.
To be fair, there are both conscious and unconscious differences in between Joe and Apeiron. The conscious is obvious - Joe is literally using illusions, potions, shapeshifting, and even the assistance of the Mist to hide some truly ridiculous features, a list of which is such a pain to list that I wouldn't even bother. Just know that if Joe didn't hide his actual appearance, people from
the next city over would notice.
And there's the unconscious difference. It's actually there in Apeiron too, and baffles those that see the Joe in Apeiron all the time like it did for the Undersiders, Uppercrust, and more recently Dauntless, but there is an easygoing and chill attitude to Joe that isn't just his Doormat tendencies. Considering the public has mostly only seen the more mercenary and warlike figure of his Apeiron persona, nobody would ever think that Apeiron is the kind of regular Joe that would help out somebody feeling awkward just to be nice or have romantic troubles over a messy not-girlfriend. But when it does show up as Apeiron, it's so seamless that people are shocked when he then turns to do something ridiculous and they are reminded that yes, this is the Titanium Ape we are talking to.
As a reminder, this is basically how it went:
Joe:
jokes around, eats pizza with them, grumbles about their timetable
Undersiders: Can only stare in bafflement as he then turns up with more tech than the entirety of the Toybox and power armor that had been just a joke.
Joe:
talks about music choices and complains about PRT interference
Weld: Bewildered as this man he has never heard of casually designs seating and heals him under the sea.
Joe:
casually chatting with Uppercrust about villains overcomplicating chess and alcohol choices
Uppercrust: Shocked as Apeiron casually throws in major superpowers into Thurin Ist as "quality of life" add-ons.
And then there's Dauntless. Poor Dauntless who got the full Mystic Cryptic Sage thing immediately after Joe had sympathized with him over similarly unique power problems and the difficulties of having to hold back now for the future. There's a reason why Uppercrust described knowing Apeiron in person and being his friend to be just as tenuous as being his enemy, because Apeiron can switch so quickly from being a normal Joe and SUPER TINKER GOD without any warning.
