Marvel's The Defenders: 23 Easter Eggs You Probably Missed

12. The Piano

When Matt Murdock and Jessica Jones go to visit John Raymond's family to try and follow the trail of Jessica's investigation of his link to Midland, they are welcomed by Chloe Levine's Lexi Raymond who tells them her father was an insomniac who used to play his piano in the middle of the night. Inconsiderate.

Anyway, Matt then sits at the piano, because he has somehow worked out that that is important and plays a tune, discovering that there are blue-prints hidden inside the piano's body revealing the secret beneath Midland Circle's building.

Rather playfully, the tune that Matt plays is The Defenders theme tune. How very meta.
