The IV fluid bag that is hanging for Kelly while she is in the hospital before Brandon sees her after her dressing changes is well past expired. The expiration date is for December 1987 and since the show is supposed to be present day that would make it approximately 7 years out of date. The hospital would have received a very large fine for just 1 bag of expired fluids.
Andrea tells Brandon that this is Hannah's first Hanukkah at home, insinuating there was a Hanukkah while she was in the hospital or somewhere else. Hannah was born at the beginning of summer, spent the summer in the hospital, and is currently less than a year old. This is her first Hanukkah ever.
