Jason looked at Leo like he was the first thing he'd ever seen - it technically was.

Piper was calling his name - Thalia gripped his hand tightly in a way he vaguely remembered from when he was an infant, Leo holding up.... three fingers?

All he saw was an almost nervous system with a faint outline of a person holding up three wirey lines.

He smiled and said three - though he couldn't hear it, he knew they heard him.

Ju- Hera had left them for a moment, as requested by Piper.

He tried to blink away whatever was wrong with his vision - the effect fades albeit he still saw the wirey lines in place of actual people - just the now clearer outline of Leo in front of him.
