Like... Sherlock's so stupid he forgets to eat when on cases cos he clearly can't multitask... or something. Obviously I'll leave the insults upto filler, but clearly Sherlock doesn't need Mycroft's diet because he simply doesn't eat half the time... so yeah, I'd like to see Mycroft return the comments Sherlock's always shooting his way. Ah, the brotherly love...
Mycroft starts returning comments about his diet with Sherlock appropriate ones
