"Well. I think when they go to look for the blood they'll see the giant gaping hole in the wall. Also, where are YOU going? Hey, come back here!"
Follow him
1 - you follow him around corner after corner after corner, and then you lose him, and you have no idea where you are, curse all the twisty passages being alike. But then you hear a knock, and a shout and a crash, and you think you can locate the sound.
"I don't trust the guy who saved us. This could be a trap, so I'll make sure it's safe!"
Rush over into the store room, and lock it from the inside. Then begin sloppily dissembling all the items in the room.
"Yep, can't be too careful! All this stuff could be rigged with explosives, so I'll risk my life to protect us all!" Expo says all this with a proud heroic grin on his face.
5 - You enter the storeroom, lock the door and start disassembling stuff, because it is in danger of exploding, but its a big storeroom, and the robots follow you and repair stuff, so good luck getting all of it.
Enter carefully the store room and look for something useful, specially weapons.
3 - You start to walk to the door but then the crazy person rushes past you and locks himself in, so you decide to take the door off at its hinges. Well you took the hinges off the door but now there is a big heavy piece of metal in the way.
Stop the guy from locking himself in the storeroom.
With force, if necessary.
2 - You try to trip the crazy guy before he locks himself in the storeroom but you miss
Knock on the store room door, grumbling
6 - You knock on the door, pretty loudly, and your knock echoes down the hall but hey the door fell over and you can enter the storeroom.
Susan takes a deep breath, before shouting at the man trying to lock himself in the storeroom.
"I am not going to, I will not die just because some guy with a hero complex is going to kill us all."
Shout at Expo Sable.
6 - You shout at Expo, loudly, louder then the knock and it echoes down the hallways but then you stop as the door falls forward with a loud crash.
Superman costume.
Go to the storeroom.
4 - You go to the storeroom door which is locked but then there is no door anymore so you step inside. The storeroom is huge, you can't see to the far end of it, in any direction except the one you entered in, You spot Expo disassembling stuff and a couple robots reassembling stuff after he leaves it. A robot with runes carved on it walks up to you and asks,
"What would you like?"
