A week after the virus spread Xiao gets bitten by a zombie and transforms into one, but he still protects you at all costs despite being a zombie. He doesn't want you to end up like him or die. Xiao doesn't speak but communicates with you by gestures and small gifts and trinkets that he thinks would help you survive. He whines, groans or moans to communicate. He is agressive to anything and anyone but you. Xiao just wants to be by your side, even if he's not alive anymore.
