A music therapist’s gentle voice fills the room with “The Itsy Bitsy Spider” to a backing track of ukulele and heart-monitor beeps.

Bitsy Von Muffling is there, too, and it turns out that the text messages Carrie has been receiving from a mysterious older man all episode are from Bitsy’s former beau, Marlon, whom Bitsy is angling to set Carrie up with.

He is known as “the human tripod,” Bitsy says, and she has photographic evidence to prove it.

It turns out, though, that, like Bitsy, Carrie was invited only for her newly “deep pockets.”

A 1-to-1 ratio means notes are evenly spaced, like in “Twinkle, Twinkle, Little Star,” but a 1-to-2 ratio means the time from one note to the next is uneven, like in “Itsy Bitsy Spider,” Dr. Roeske explained.
