Sera

you see her during Extermination, you think it was quite unexpected, she seemed to be protecting someone and her sister Emily (Adam): "where are they?!, I know you're hiding them Sera!" (Sera): "I'll never tell you... it's only to protect my sister." (Adam): "Show them to me.....NOW!" (Sera):"No!" Adam puts the spear up to her throat, he looked angry (Adam):"show me where they are or else...." (Sera):"it's for your own good Adam..." Adam applied more pressure (Adam):"TELL ME NOW!"
