Maria: Mister Babbage?
Brian Babbage: Maria.
Maria: Oh! You're awake! It's a miracle. I came as soon as I heard. Sorry about your sister and your brother.
Brian Babbage: Thank you, Maria. The doctor just told me about them. I can't- I can't believe it.
Maria: I won't stay long. I just wanted to welcome you back. And I brought your mail.
Brian Babbage: What's- What's that?
Maria: I'm sorry, I started to open...
Brian Babbage: It's a bomb. It's a bomb! Get down! Get down.
[Randy pulls back the hospital curtain to reveal Monk, Sharona, Stottlemeyer and Agent Grooms]
Adrian Monk: I can't help but wonder what made you think that was a bomb, Mr. Babbage.
Lieutenant Disher: Brian Babbage? Good morning. You're under arrest for the murder of your sister, Amanda.
