The silver-streaked light brunette Detective Inspector Greg Lestrade may not have been a genius like either of the Holmes brothers and may be able to 'observe' the way they do, but he still 'sees' more than they would (grudgingly) admit. Sherlock and John, as 'the World's Only Consulting Detective' and his assistant/doctor/flatmate/blogger/liaison/friend, have changed since Sherlock (not that he would ever say so, not in the way it had) came back, yet are very much the same. The proof was here, in this case, in the way they acted, and why.
They were silent as they exited the cab, Sherlock hovering slightly as if to make John didn't leave, but he was waved off towards Lestrade as the shorter man paid. John was continuing whatever they started in the cab, "a head in the fridge, next to the food Sherlock!" "No Sherlock, we cannot (insert various body parts/chemicals for experiments)" just some - as he paid the cab driver, Sherlock moving towards the (XYZ) crime scene. John followed after Sherlock, leaning on his cane heavily, eyes always on his friend's back, never noticing Sherlock's own glances. The grey-streaked blonde man was smiling as he jogged after Sherlock, who was smirking slightly as he held up the crime scene tape for him, the limp he'd first came with gone after the first case, 'Study in Pink', eyes always met without hesitance. Donovan stopped the two, saying something that seemed to annoy Sherlock, and have John narrowing his eyes in silent anger before pulled Sherlock past, a faint smile on his face as Sherlock made some arcebic observation in retaliation. Donovan 'greeted' Sherlock with "Freak's here!", having John ask if she was still sleeping with Anderson, with tightly controlled anger in return, Sherlock responding that it was obvious she was, before Lestrade retrieved the two, pretending not to notice the two's shared smirk. Walking onto the crime scene, John released Sherlock as if he just realized he was still holding onto him, before gesturing toward the body, as if to say 'Go on, do your thing'. The Detective Inspector led them over, the two following side-by-side until Sherlock sees the body, beating them there but not starting until John was near. He got to the two as Sherlock started his observations, leading into how the neighbor did it over the victim's rejection of his advances, then John's quiet, unintentional, soft "Brilliant". John's face showed his unabashed awe that never lessened no matter how many times he heard the taller man, which had Sherlock preening proudly after every glance, before they were informed it was the nephew over the inheritance via poison in the hand cream, "Brilliant!". John's face held awe, no less than before, Sherlock standing a little taller as he realized his friend still wasn't like the rest in regards to his observations even with his absence, before he led John out, asking if he wanted to go to Angelo's. John smiled softly at his friend, faintly embarrassed at saying so aloud, so loudly, as Sherlock gave him clues to prove it was the nephew, before leading John out, John suggesting Chinese take-out. John bumps shoulders softly, his voice barely carrying loud enough to be heard, except by Sherlock, "Yeah . . that sounds good. Can we eat more than a sixth of a meal combined? Then let's go home.". The two walked closely together, Sherlock scoffing at his 'transport's' boring need for food but ultimately agreeing as long as long as they hurried home, that there was an experiment he had to tend to.
