Contact.

[ will sounds like he's giving a lecture when he comes on the screen. he's looking directly into the camera — it's easier to make eye contact with a device. ]

That's the key to all this. If you're receiving foreign sensation, you need to track down the person it originated with and make skin-to-skin contact. It'll stop the side-effects, and eventually — hopefully — break the connection. Doesn't have to be more personal than a handshake.

[ a pause, and he glances down, off-camera, visibly discomfited by the fact that the hand not holding his device is in the grip of another. ]

An... extended handshake. Whatever timer this thing is working on, we think letting go resets it.

[ the screen’s upended as sherlock hijacks the device, settling on his face (at an admittedly slightly awkward angle) a moment later. ]

But in the meantime— I’m sure you’ve all noticed that the physical links are current, unlike the memories, and arguably offer us a great deal more control. Passive sensations are the exception, but if I were to hypothetically hit my hand — as our resident neurologist has demonstrated — then Mr. Graham would feel it. [ and by hypothetically he means he's tested it, several times. ]

In the case of mutual sensations, like, say, holding one’s hand, this creates a unique feedback loop; the sensation of their hand in yours, and yours in theirs, et cetera. [ speaking of hand-holding, holding will’s hand is getting in the way of his usual gesturing; the screen's unsteady as a result. ] While I'm reluctant to test the theory with present company — no offense — I imagine this could apply to other neutral or positive sensations. If one were to engage in sexual intimacy with their link partner, for instance, then the moment of—

[ in another blur of abrupt motion, will takes his device back — and also his hand. no offense. ]

Better reset the clock to zero, Mr. Holmes.

[This is a really crooked video feed, and the jerk recording it didn't even bother to wipe his nose before he started, as evidenced by the fact that his face is maybe a little covered in blood. Gross.]

This is a--this is a PSA--that is…public service announcement, for those of you not--not in the know, as far as acronyms are concerned.

I'm just going to start listing things, and if any of it sounds familiar, please come to--to collect your memories, I don't want them. I had more than enough of other people in my head back home, I didn't--

[Right, just give him a second to try and take care of that nosebleed.]

It didn't start out so bad, but now I'm pretty sure I'm dying, or my head is going to explode, or I'm going to leak out all my blood through my face, so if we could all--could get this sorted as fast as possible, I'd appreciate it.

[Here is a big, gross, snotty inhale, as if to emphasize that he is, in fact, dying. It sounds like SSNNNRRRKKK.

When that doesn't work, he drags a hand across his face, leaving an attractive smear of red up his cheek.]

If anyone has, at any point this month recalled not having any arms or legs or being a sort of--sort of ball-shaped robot, that's me, hello, and I'd like to--like to talk with you as soon as possible. Confusing, yes, I know, but seeing as I can't really put owners to the memories of…the monster fights and the gang fights, and the--you lot get in a good deal of fights, don't you?

[Cough. Sniff.]

Bill Murray. Is the bloke's name. If that sounds familiar to you. At all. You had a pretty good time, with him? In his house? To my understanding? Then he died. Your friend? Your friend shot him, but, uh, if I had a friend who went around shooting my other friends, I would sort of--sort of reevaluate where we stood, as far as our friendship was concerned. So, uh, sorry for your loss, either way. You can come get your memories, now.
