While Lily was away, Elizabeth, under the request of Delfin to find out what really happens to Oscar, coerced the rest of the in-house staff to find out what Lily made Oscar drink. As they rummage through the bedroom, Elizabeth found the bottle of the drug with one tablet remaining, and went to Delfin's office to give him the crucial evidence: the tablet. But along the way, she accidentally dropped the tablet and was stepped on by Oscar, so she and Ambo decided to replace the drug with paracetamol before Lily could catch them red handed, which led to reduced headaches, but retained the rest of symptoms.
