When Catherine is interrogating the daughter of the murderer, the daughter's hair changes between shots. From over her shoulder to behind her shoulder and then back again
Cat introduces Tess to JT in the women's locker room and she does not appear to know him. (This is emphasized in future episodes when Tess repeatedly calls JT 'TJ'.) However, Tess first met, and questioned, JT in the Pilot when she and Cat followed a lead about Vincent Keller to JT's warehouse. Tess also saw JT without his glasses in Evan's lab in 1.08 Trapped, then helped Evan and a sketch artist come up with a composite drawing of JT in 1.09 Bridesmaid Up.
