Tiffany thought about the situation they were getting into strategically. She was trying to think of a way to kill these zombies without attracting more. Liam looked like he was going to throw a Molotov, Karis was obviously going to do nothing that would risk her life and Zack was still fast asleep. All she had was her hunting knife. "Maybe, if I distract them that'll give you time to throw the Molotov and kill them quickly. And then we can all try to get inside safely."
She thought the least she could do for them was buy them time. "So if I go out first and make some type of noise they'll be attracted over to my area. Then Liam you light the Molotov." Tiffany explained with a somewhat worried look on her face.
