The thing that touched me most about this scene wasn’t really the fact that Sherlock tried to call for John but rather the fact that John knew that there was something wrong. That Angelo kept insisting that it’s all “part of the plan” and that John, after knowing Sherlock for about a day, knew that there was something wrong. That he knew Sherlock that well after a single day of knowing him. That shows a real connection between them and that’s what I loved most about this scene.
