Shortly after April Meaddows witnesses the death of Valerie, she asks her medical colleagues, "What's the prognosis?" Since Valerie's head just blew up splattering blood all over Meaddows, the prognosis is "she's going to remain dead".
After Valerie has a strange experience in the bathroom, she is pictured shakily coming down the stairs of the office, where the security guard asks her what's going on, etc., to which he receives no answer. she continues down the stairs, while he goes back up to investigate. He is next shown looking in the bathroom, but she never told him a word of what happened that would have led him there.
