I was watching The Hobbit, (fourth time actually. Yes, I know... But I love it :3), and I couldn't help but point these things out.
Hope you enjoy them, sorry this is so late!
Disclaimer: I don't own Sherlock, The Hobbit, or anything that could get me into trouble... ._.
Why John is a hobbit:
John couldn't cope with Sherlock's death and so Mycroft creates him a new life in middle earth and sends him off.
Lestrade, , Sarah, anyone who could care thinks that John was overcome with grief and had commit suicide because Sherlock was EVERYTHING to John. (Johnlock)! He'd kill for him, after all.
John's personality and habits shine through his cleverly painted mask:
When Radagast the brown comes to warn Gandalf of the necromancer, Bilbo has this look on his face that clearly says, 'the fuck, Mycroft?'
When Bilbo stabs the warg in the head he looked truly terrified; not just because he killed a giant dog-thing, but because he has PTSD and was remembering Afghanistan. Also, he probably realised that he prefers guns.
He's protective of his jam; John LOVES jam. When the dwarves were taking all of his food he specifically said, 'not the jam!'
Near the end of the movie he lists a couple of things he misses: 'I miss my armchair.' What he really means by that is THE armchair that is back at Baker Street. He misses life at Baker Street far more than life at Bag End.
Gandalf: I'm looking for someone to share in an adventure...
Bilbo: (internally) God, yes.
Mycroft watches John's progress and is shocked to find that he is not living a quiet life at bag end, but has become loyal very quickly to the dwarves and has gone on an extremely dangerous adventure; worse than the hell Sherlock would have dragged him through. John went on the journey because he remembered all the adventures he used to have with Sherlock and after much consideration, he went; finally being able to realise that he quite missed the danger.
Mycroft knows that John is not coping well in this new environment, and he would remove him from the surroundings, but he knows that this is the only way John is going to see Sherlock alive again
Guys, I just want you to know: Moriarty is a spider. Those giant spiders that attack Radagast's home are part of his elaborate web. Moriarty wanted back his pet. (Mormor)!
It's nice that Radagast saved Sebastian, but little does he know, that hedgehog is a cold blooded killer; a sniper working for Moriarty.
Maybe he should have left him outside...
