Character mistake: Doctor ordered a BMP, a CBC, and a CHEM 7. A BMP and a CHEM 7 are the same test.
Continuity mistake: After Max bumps into the hospital tray table next to him as he's getting up from a crouched position, the table crashes back upright, but in a subsequent shot the table is toppled over on the adjacent hospital bed. (00:31:20)
Character mistake: When Max is speaking to his new cancer doctor, he makes a mistake while talking - instead of saying "when my baby gets here," he mistakenly says "when my gets here." He missed out the word baby. (01:50:00)
Happy Place - S1-E19
Continuity mistake: Max is about to take a bite out of a donut (chocolate frosted with half covered in sprinkles) when Helen interrupts him. When speaking with Helen he doesn't get to bite into it. We see him holding the donut. In subsequent shots, we see him holding the donut in different directions and a bite is missing from two different locations although he never bites nor do we see him chewing. In his other hand, it seems as if he is holding the piece of missing donut. (00:12:41)
