John watched Sherlock with a look of disdain. He'd gone off to his mind palace, hadn't resurfaced, and left Greg and John sitting in an awkward silence. Usually, Sherlock told them to get out if he wanted to lock himself in his palace, to sit on his throne, but it had been all so sudden, a break in the case, a realization, and Greg and John were left sitting in that awkward silence.
Greg cleared his throat, looking at John as if to say something. Sherlock held up a hand, stopping him without words- he was still partially in the real world, then. Greg rolled his eyes and John sighed, making to stand. He'd just go wait outside, then. Sherlock's hand suddenly closed around his wrist; John almost jumped before he glanced down at Sherlock's hand. He then looked back at Sherlock, frowning.
"Need you," Sherlock muttered, not opening his eyes. He didn't look like he'd said anything at all, in fact, but the look on Greg's face was enough to prove to John that Sherlock had really said that.
"What?" John replied, somewhat in surprise.
Sherlock's eyes snapped open. He looked at Greg first and then John, noticing his grip on the latter's wrist. "I said, I need you." He relinquished his hold on John's wrist; John pulled his arm back into his own lap and rubbed his wrist. "Although, I find myself a bit hesitant to bring you into action... It is more dangerous than usual..." Sherlock murmured, frowning to himself.
"I'll come," John replied immediately, standing with Sherlock.
Sherlock's eyes assessed him with a hard look, a calculating look, for a few, tense seconds. Then the detective looked away and looked towards Greg. "Might send an ambulance. The probability of needing it is high."
Without another word, Sherlock stood and brushed out of Greg's office, John following behind him. "Sherlock? Sherlock, what are you planning?" The silence was dreadful, in both senses of the word, because this silence meant that Sherlock had something not so good planned. Not so good that they might need an ambulance. "Why are we going to need an ambulance?"
Sherlock finally spoke up, although he didn't look back. "Just follow my lead, and stay behind me."
John frowned and picked up the pace, falling in steady next to his companion.
Ahhh, overlook the slight OOC-ness! -Grin- I think this would definitely take place after Empty House.
The general worried-to-bring-you idea is borrowed from Sherlock Holmes and the Adventure of the Speckled Band.
As ever, looking forward to your thoughts! Up next, Sherlock's Cold! (I suppose I should call it John and Sherlock are Cold. But, no. Haha)
