It was an inside joke. Each of the 'batfam' had a weakness. No one - not even Alfred - knew Batman's. Damian's was easy; Damian's was the heat. Couldn't stand it; he got way too hot way too quickly. Tim's was the dark. Was never found asleep without either a light on or the door open with a light on outside. Jason's was water. He couldn't hold his breath and had panic attacks when he had prolonged contact; say he was in a pool. Dick had two; cold and poison. He froze in twelve degrees (C) and never left the house with a jacket on. And the poison traveled at least three times as fast through his bloodstream as he didn't clot easily. Alfred had one too; as impossible as it seems. His was his age; he was nimble, yes, quick, yes, agile, yes, but occasionally his limbs cramped, or he had trouble breathing. ---Ⓜ️ for blood, gore etc, and bad language! ---
