Dr. Coomer is a bubbly, charming old man with his heart in the right place most of the time, though his coding as an AI leaves him to quite often repeat basic phrases, forget simple mechanics, or speak to Gordon in manners that can only be compared to that of a tutorial NPC. When he does think for himself, his dialogue is often humorous and witty, and very often responds to questions with nonsensical answers or repetitive dialogue mentioned before.
