If anyone has seen or heard from Jack, please let me know.

[Private - Aisling] 
Jack said he was going back to have a look at the ruins. Have you seen him? I haven't heard back from him and... it's been a while now.

[Private - Team Tardis and Torchwood NM]
Attempts to reach Jack through his phone have failed and I can't locate him. He said he was going to take another look at the ruins, but he was supposed to check in before he went down. He's been missing a while now. If any of you know where he is, let me know as soon as possible.

[Private - Jack]
Jack? Jack, answer this. I know you said you had to do this alone, and I was trying to let you but- at least let me know you're all right. Don't give me that I'm Immortal line. We both know that doesn't necessarily mean anything in a place like this... Jack.

Please.
