I agree with Kitty on both posts. You could most likely join as another character, but seeing as Jeff is taken, not him. You also should have put a bit of a warning in the bio, to be honest. Sorry. ^^'
On another note, I'll be bringing back 895 and Crosshatch. Here's the CSes, just so it's easier to see:
[Hider=SCP 895] 
Name: SCP 895, Camera Disruption, The Coffin
Age: Unknown
Appearance: 
He can still speak by tweaking the stitches so they're loose. He's about 6' 11'' (same size as the coffin. And holy cow is he tall!) and his eyes do swirl. He's rather thin and pale, even for a SCP. The wooden, almost antique-like coffin he has is technically his home and he seems to sense those near it even if he is somewhere else.

Abilitys: 
◆ SCP-895 causes disruptions in video and photographic surveillance equipment within 50 meters similar to vivid, disturbing hallucinations with variable durations and regularity corresponding to the camera's range from him.
◆ Within a range of 5 meters from SCP-895, footage captured can cause severe psychological trauma and hysteria in most subjects. These disruptions do not extend to observers physically present within the area.
◆ He can move rather quickly and can blend with the shadows well to avoid detection. This is how he managed to avoid getting seen in the Facility before he escaped. He knows the information on most SCPs after hacking into the database with ease, despite the security on it. So, he's a pretty good hacker.
Bio: [url=http://www.scp-wiki.net/scp-895]It's technically this.[/url]
Weapons: He doesn't actually have any physical weapons. To be honest, he wouldn't even know how to shoot a gun.
Weaknesses: 
◆ When someone opens his coffin, an unbearable pain is sent through him until it closes, this is why he hid it underneath the ground in a basement to keep it alone. 
◆ He can't stand water and he either tenses up and freezes in place or heats up and gets away from it as quickly as he can. 
◆ His powers can only work through microphones, cameras etc. They don't affect anyone physically nearby.

[B]Weakness:[/b]
◆ If she doesn't know a certain bit of information, she just focuses on getting that, ignoring her own health.
◆ She can only travel to and through a computer if it has the email she sends to victims. If one computer got sent the email yet there's more in the house, it only works if they're on the same connection.
