-- the aphasia...new to me and well explained; -- how Harry and Severus both have become 'creatures of the night'; -- how the relationship slowly developes; -- Harry's understanding that Severus is important to him; -- how they understand each other; -- Severus's tough love towards Harry; -- Harry's taking care of Severus (beautiful scene, that, the massage and the putting to bed); -- how they come together at the end, taking chances...with their future up in the air (sorta).
