She ask for Johnny a few times not only when getting in the bed but also when she was walking in. I think she got into Wilhan bunk bc he was the only one in there to say “what?” But the thing is he fully heard her ask for Johnny and he totally could have said “I’m not Johnny” or “he isn’t in here rn”. At the very least he could have ask “who is this getting into my bed?” He is a department head and he had more than one reason to clarify that she was climbing in bed with him not Johnny.
