Amata wakes you up and lets you know that something bad happened - your father escaped from the vault, and the vault guards are also coming after you. Because of the recent change of events, you need to escape from the Vault - a shock to your conditioning about nobody ever entering or leaving the Vault.
Collect your stuff, and head outside your room - you'll realize the severity of the situation when a security guard attacks you; they want you taken out.
To escape, you need to obtain the overseer's password - you'll see him interrogating Amita as you pass by the interrogation room.
Once you have the password, you can open the passageway to the vault entrance and open the exit.
- On your way to the exit, the leader of the tunnel snakes needs help with rad roaches (because he is partially nyctophobic). Feel free to deal with that.
A Medical bobblehead is available within the vault - this is your second of three chances to obtain it.
