She chooses the grate

“There is no way that I can open the door silently, and whoever set the trap would know where it leads in any case. I think they'd be sending more goons down here to deal with me soon, and they would be ready for me. I need to escape and get help.”, Alessandra thinks to herself.

She quickly inspects the grate, and seeing it is stuck uses the crowbar to open it.

She squeezes herself through it and exits the trap room.
