In Batman & Robin 18, while going through Damian’s things, Bruce finds this note.
The idea of Clark sending Damian a list of movies he might find inspiring just rips my heart out.
The movies include titles about adolescent rebellion (On the Waterfront, Rebel Without a Cause), kids overcoming major odds to become successful and heroic (My Left Foot, The Miracle Worker), movies about justice, compassion, and heroism (To Kill a Mockingbird, China Syndrome, Gorillas in the Mist, Cool Hand Luke, Lawrence of Arabia). These are tough, challenging movies, not patronizing kiddie fare.
There was pretty much no hint before that Clark had the kind of relationship with Damian that would prompt a note like this (they met once in canon that I know of)…I wish I knew the story behind this.
(This was a beautiful issue by Tomasi and Gleason, by the way).
ETA: Gleason has confirmed that CK is actually a college-age Carrie Kelly! OK, that’s…not what I had in mind, but is interesting…
