“Don’t forget me in my solitude”

LANE: Don’t forget me in my solitude.
RORY: Never.

A possible reference to (In My) Solitude, a 1934 song by Duke Ellington, with lyrics by Eddie DeLange and Irving Mills. It is considered a jazz standard. Ellington’s second version of the song went to #2 on the charts of 1934. Covered at least 28 times in the 1930s and ’40s, it was recorded several times by Billie Holiday; one of her renditions was chosen for the 2021 Grammy Hall of Fame.

Some of the lyrics seem to describe Lane’s emotional state very well, perhaps even providing a disturbing insight into her present thoughts:

I sit in my chair
I’m filled with despair
There’s no one could be so sad
With gloom everywhere
I sit and I stare
I know that I’ll soon go mad
