Eh, I'll leave my post as it is for now. If Orchid can find out what is the right key to open a door, than she can use the same key to open up the other cell doors and free the other trapped people quickly and easily. Presumably Orchid just examines the door after Angus throws it off it's hinges. Though I will edit one thing in there to make Angus' vendetta more manageable. 

Edit: There we go. Angus now has Orchid's glaive so he can rip and tear a bit more effectively. I know it's not his sword but it's better than nothing.
