Not with My Sister You Don't - S1-E19
Character mistake: Howard Borden goes to Bob's office and says it's the first time he's been there. In fact, he had come to the office to address Bob's "fear of flying" group in the first episode.
Other mistake: Anders, Blake, and Adam help promote Alice to become the boss. Before becoming boss and cleaning up, she had a very casual attitude and is shown wearing informal black, rebellious clothing. However in 3-10 "Flashback in the Day", when Anders, Blake, and Adam first meet Alice she is the same strict, formal boss seen predominantly in the show. So basically TAC in the Day makes no sense, because Alice was already boss by that point in time and already had met the gang before their first day at work. She recruited them, after all.
