Claudia tells Steve that she got locked up for saying that her brother was calling her from another dimension and that it didn't help that she was right. However it was previously established that her stay at the psychiatric hospital was voluntary.
When H.G. rescues Adelaide, Helena tells her "bravo". But H.G. would know that the correct compliment for a female is "brava".
Adelaide and her expertise in Kempo - a fist/punch oriented martial art - are mentioned several times through the episode. However at the end, she is seen demonstrating a punch to her father in the background. The entire form of the punch - the arm movement and positioning - would only be possible from someone with zero training in any sort of fighting.
