"Fly me to the moon, and let me play among the stars.
Let me see what spring looks like from, Jupiter and Mars."
"Geez. We really have to update your music collection, Steve."
"In other words, hold my hand.
In other words, darling kiss me."
"Such a pain in the ass, Rogers."
"Fill my heart with song and let me sing forever more."
"Please don't."
"You are all I long for, all I worship and adore."
"Awe, you're making me blush."
"In other words, please be true.
In other words, I love you."
"Using the L word already? You could at least by me dinner first."
"How 'bout ration packs by starlight? My bunk, eight o'clock."
"It's a date. Now let me finish my work out here."
"Whatever you say, Boo Bear."
The line was quiet for all of two minutes before Bucky heard softly,
"The stars are aglow and tonight how their light sets me dreaming.
My love, do you know that your eyes are like stars brightly beaming?
I bring you and sing you a Moonlight Serenade."
