Yearning (Umbrella Academy - Klaus/Dave
Klaus wakes up sometimes and forgets Dave is dead.
He sometimes forgets he ever met him. He forgets about Vietnam.
(Not really, but for half a second. A lot can happen in half a second. People can die in that time. Their body left to bleed out through ragged, gaping, messy holes under your hands, torn apart by war and fellow humans. It happens, look it up.)
Sometimes on too sharp mornings, Klaus feels something too clearly and before he can shut it down his brain has named it yearning, and sometimes it would be easier not to know anymore.
