When Peyton's real identity is revealed to Claire, in Emma's room Claire is packing Emma's suitcase. From outside the bedroom door, as Claire packs the bag, she tells Emma they are going away for a few days and that she can take Dolly with her. However, as she says this, her mouth never moves.
When Claire is showing Peyton to her room in the basement, she points towards the laundry room to the right. However, when she's folding laundry and looking out the window at Solomon and Emma playing in the yard, she's doing laundry in the garage. You can see the garage structure when they pan the yard for that scene.
What Claire has isn't asthma it is actually panic attacks. Asthma attacks are not brought on by sudden stress or anxiety, they are brought on by bacterial, infection, stuff of that nature. You can tell with how quickly she is breathing during her "asthma" attack that it is a panic attack and not an asthma attack.
