Midnight's Trypanophobia(read desc. for more info)

"Trypanophobia is defined as extreme fear of medical procedures involving injections or needles. Although sometimes also referred to as aichmophobia, belonephobia, or enetophobia, those terms generally denote a fear of pins, needles, or sharp objects while tryphanophobia also includes the medical aspect of the fear." according to specialtypharmacytimes. Yep. That's what Midnight has. First, she turns pale and becomes frozen in fear. Next, she curls up into a ball and develops a five-minute subconscious state. Finally, she says the phrase, "It's only a needle," repeatedly. If you put root beer under her nose, she'll snap out immediately.
