#Emma will also sometimes call him Sleepy Cyclops but that's meant to be more of a sweet callback

I headcanon that at first Ray is adamantly against the use of nicknames and pet names for himself because he thinks it's silly.

"My name is Ray. It's literally three letters and one syllable long. Just call me Ray."

But Emma can't let that stand. She has "sunshine" and "Em," Norman has "Nor," "Norm," and "Boss."

So her proposed solution is for Ray to change his name so that "Ray" can be a nickname and show of affection. Ray balks at the suggestions she litters throughout their conversations, addressing him as Raymond, Rayner, even Raybert at one point.

Norman is more deft in his timing so the first time he drops a "Raymond" during one of their chess matches he ends up on the receiving end of Ray channeling Isabella with this look

He does eventually come around to them calling him Sunray.
