You’re Dr Bright twin sister and you work at the foundation with him but what he didn’t know is that you could understand everyone of the SCP’s that couldn’t speak common.

the O5’s had decided to put one of the researchers in with SCP-173 and they decided to put you in there by yourself, so that means if you blink or look away from SCP-173, you’re dead.

O5-1: “remember, try and not blink for 3 minutes then we will let you out and put you up a rank and you will be on the same level as your brother” he spoke over the intercom for SCP-173’s containment chamber, then the intercom turned off and all the O5’s were listening from the cameras and didn’t have them on so SCP-173 will attack if you stop looking at it.
