When Colleen goes to visit Misty in hospital to apologise for being responsible for getting her arm cut off, there's a nice little Night Nurse Easter Egg in the background for the most eagle eyed viewers.
The white Patient Care Board on the wall behind Colleen has the nurse on call listed as L. Cater.
That clearly refers to Linda Carter, the original Night Nurse who became the first one who superheroes - including Luke Cage and Iron Fist - would turn to for secret medical assistance.
