Maybe it’s my alcohol addled brain right now, but this sequence really touched me. Red Hood was there for Bizarro at the drop of a hat. Bizarro is slowly losing his smart mental faculties and is about to revert back to his simple and slow self. Having a friend be there for you to endure it, even promise that everything is going to be alright, is comforting. Never mind Red Hood will never be able to guarantee his promise. Just being there is enough.
