The detective appreciated John's care and snuggled into the travel rug. He could see that his friend had his doctor's head on and was not at all happy about him declining to take medication.
“Whatever the poison is, John, it's not likely to be something common because it was meant for me. The culprit would know that with my knowledge of chemistry I would spot a common poison immediately which means I can't take any medication until Molly identifies what the substance is” Sherlock explained. he hadn't wanted to worry John any more than necessary but he wanted his concerned friend to know he wasn't just being a difficult patient.
Molly sounded very busy in the kitchen in the makeshift lab which was complete enough for much of Sherlock's needs. He was very relieved that she seemed to have everything she needed. John then came back with pen and paper and he was about to begin dictating when Molly called John to see what she had found.
“John, go, see what Molly's found.” Sherlock urged “I'll be ok on my own, I won't try to get up”. he promised.
