Subject is counting.
General Observations
Bill counts.
It is unclear what he is counting, or why, but the counting continues. He monitors situations with a watchfulness that suggests he is keeping track of something no one else can see.
He also tastes your elbow for sauce before biting.
This is not explained by the counting, but it is documented.
Notable Incidents
The Summer of Porch Entertainment
When the peafowl lived on the screened porch, Bill claimed the chair in front of the glass doors as his observation post.
He watched the birds for hours. Counting, presumably.
Ted also wanted this chair. Bill won more often than seemed statistically fair.
The counting may have been strategic.
Current Status
Still counting.
Still possibly a Flerken.
United with Ted in skepticism.
Known associate: Ted (united in skepticism).
