Update: B5 has been disposed of. Their room has been breached with high levels of contamination. Their room housed a molded, identified as the expired B6, and has been dealt with accordingly. Their waste room was the most contaminated. All faucets were left running allowing contaminated water to cover the room. B5 was found in their tub bathed in the mold. it is unsure when they were infected, much less why they decided to do this.
Note: THe storage room was riddled with broken rations. It appears B5 was tearing through their rations at an abnormal rate, unbeknownst to us. It is unsure as to what made them do this.
Update: We will attempt to reach the D-level to retrieve the survivor, D4, from that floor.
