My favourite support (so far) in Three Hopes, but felt Tears in Moonlight fit the opening of this scene more than Soliloquy, given Dimitri's pain as he shares with Felix the ghosts that haunt him.
0:21 It tears me up! While Dimitri doesn't go crazy in this timeline, he still is haunted by the ghosts of his late allies. Heck he even thought Felix was Glenn's ghost.
