The Doctor was relaxing in Dobermann's room on a day off and came across some old photos.

Huh... So you were in a band way back when, then?

That sure takes me back... You'd hardly find me without an instrument in my hands in those days.

It seems like you were really passionate about it, too! That's so like you!

Though you kinda give off a slightly different vibe now, Y'know?

Indeed, the vibrancy of my younger years might be slipping away....

Ah! This one is...

...That's a photo that was taken by YOU just last week, Doctor.

Actually, you seem to radiate MORE youth now than ever before!
