Celestia is worried about her sister; Luna talks to herself constantly and refuses to go beyond the palace walls if she can help it. Thinking a kindred spirit will help, Celestia (with much additional persuasion from Fluttershy) asks Discord to spend an evening with Luna to get her to open up, even if just a little.
And much like anything involving Discord, almost none of it goes well.
