At the convent, it turns out that D'Artagnan's other two appointments are with Athos' dueling seconds. For the Queen to appear without them will cause her dishonor and may well cost Anne her life.
At the Bastille, the Cardinal meets with Bonacieux and accuses him of treachery, then upbraids Rochefort for failing to hold onto Constance; Rochefort tells the Cardinal that Anne has given the diamond studs to Buckingham.
