You didn't tell anyone that you got infected with the Flare in the tunnel, afraid of what they would think. You distanced yourself from the group, but mostly Newt - only speaking to him when absolutely necessary.

Newt noticed you avoiding him and tried to ask you about it multiple times, but you never answered his question and walked away. When he tried to ask you about it. When you tried to leave, he grabbed your arm firmly but gently to stop you.

"Why are you ignoring me?"
