Update 1
It was raining.
Not abnormal, but certainly bothersome on the day Sherlock had to get in contact with his brother. He had no way, had no phone, couldn’t risk being seen currently, and certainly didn’t have enough time to go buy a disguise in a store, nor the money, without being seen.
Instead, he was standing in the middle of a very empty, dark street waving his arms wildly at a security camera and still somehow making sure no one could see him. He gave a final huff after a good twenty minutes of flailing and trudged into a nearby wood.
He found plenty of mud and his hair was just long enough that he could pull it all over and make himself look homeless. He grimaced at his reflection in a puddle once he returned to a more occupied street, but it had worked. He wasn’t recognisable to anyone who may have just seen a picture of him in the papers.
Sherlock heaved a relieved sigh when the first payphone he passed rang loudly. He jumped towards it and put the phone to his ear.
“Mycroft!” he barked.
“Yes, Sherlock?” was Mycroft’s amused reply. Sherlock sneered.
“This is getting ridiculous. I shouldn’t have to wait that long for you to find me on camera.”
“Oh, I saw you within the first minute. You’re the one who assumed otherwise. It was quite amusing, however, to see you jump around like a banshee. I hope you’ll do the same every time you contact me from now on.”
“I need a cell phone and I would like a fake ID and credit card,” Sherlock seethed. Mycroft was silent. “Mycroft!”
“We agreed, Sherlock.”
“I know we agreed. I’ve changed my mind.”
Q:Hi Sherlock, it's John again. Lestrade's brought over a case I thought you'd find interesting. Just...just come back and we'll go. Please. I just want to hear your voice again.
I believe in Sherlock Holmes.
Moriarty was real.
You’re a fraud!!! People like you disgust me!! My husband’s a DI and he doesn’t get credit for real things like you did for make-believe!!!!
Q:My mind likes playing tricks on me while I'm sleeping. It makes up this hugely normal event, something completely mundane and domestic at the flat, and it puts you right in it. We act as we normally do, too, and I'm overwhelmingly happy, not even remembering what's happened. As if you never... left. ...Well, then I wake up and there's this awful moment of glee before I remember everything. Anyway, um... Yeah.
Q:I believe in you. It's all over London, you know! I believe in Sherlock Holmes!
Q:You bastard.
Q:Hey, Sherlock, this is Greg. John told me about his new habit of calling your phone when Molly suggested we all go out for a couple rounds. I figured it couldn't hurt, though I am a bit tipsy. 'Though it's not exactly like I can regret this in the mornin, you're not around to listen to it! Anyway, buddy... Yeah, I said buddy and I meant it. ...We miss you. John likes to put up a strong front, but his eyes always seem to be screaming like he's waiting for the dramatic end of a movie! Well... Bye.
Q:Hey, it's Molly. I brought John out for a bit to see how he was holding up. After a couple of drinks, he managed to tell me he'd been calling your phone as a sort of coping method. I think I'm going to have to keep an eye on him. We all miss you- sorry, no, that probably wasn't the smartest thing to say. Okay, well, I'm going to... go. I'll call some other time and leave another message. Bye, Sherlock.
Yep.
We believe in you. That is all.
