Ayla got into the ventilation system last. Keeping an eye on what was behind them all by going in backwards holding her gun pointed at the entrance to the ventilationsystem. She knew Heinrich probably didn't like it that she went in last, but she felt like she had to make sure nothing else goes into the ventilationsystem while they were still in. She mentioned John who got in just before her to keep on the look-out aswell. Nothing happened though, they could move towards the surgery rooms without any trouble. They just got covered in some weird substance. Ayla preferred not to think about what the sticky material could be. As she got out she mentioned John to keep watching the ventilationsystem. "So, what now, Captain?" she asked Heinrich with a smile. She felt weird calling him captain but at the same time she found it funny to do so.
