Some do linger where they passed -if once human or a different pokémon entirely- because they are clinging to something, while others go about freely. [There was a buzzing sort of giggle from the Rotom phone at the poke, smile moving with the sound.] You're fine- questions are natural, and asking them is a way to learn. I fear I get a little long on my answers, so I may well apologize for that beforehand myself.

They do- as far back as any recorded history can at least. There are even new records being discovered, history uncovered. [An exciting time for even some outside of that scientific community.]

It does ease some worry, at the very least- more so in knowing a decent handshake can do. [Of course he paused, briefly, in thought, a hand lifting to adjust those glasses of his out of sheer habit-] So far it seems that it may? Leaning against someone just casually while spending time together, as an example I've heard of working.
