Basically the whole episode revolves around one character's emotional difficulties and Will feeling a bit ignored by their mutual friend who is in town, all while Will's mother has suddenly left town the night before after giving a hasty, extremely vague and obviously fake excuse to her sons & other characters – read through the lens of "it's supposed to be Will's birthday" it makes all his close friends and his mother seem insanely cruel to be completely ignoring his birthday when in fact that wasn't what the writers were going for, they just didn't realize the visual date matched a line of dialog from a prior season.
