A Glass of Apple Juice

It isn't unusual, by this point, for John to come home from whatever job he hasn't gotten himself fired from for erratic hours to find Mycroft and Sherlock sitting in their flat, engaged in what neither of them would ever admit is a staring contest (though it could hardly be mistaken for anything else).

This time, though, Sherlock glances at John as if to say 'thank god you're home' rather than 'took you long enough' and Mycroft's look says 'if you'll just hear me out, you'll understand' rather than 'could you please make Sherlock be reasonable'. Neither look is at all reassuring, but reassuring isn't precisely the province of the Holmes brothers.
