At first Starsky believes him. The false step, into a door. The fall down a stairway. Hutch can be clumsy; he believes it.
When Hutch starts avoiding his eyes, then he starts disbelieving it.
When Hutch seems tired all the time, when Hutch doesn't want to go home.
When Hutch falls asleep at his desk, and jerks with fright if Starsky touches his shoulder to waken him…Starsky doesn't believe him.
He takes Hutch out to Huggy's, sits him down for beer. "When are we gonna talk about this?"
"About Van hurting you…"
Hutch hangs his head in shame.
