Merlin 4x12 teasers

Hurray -new teasers:

These usually follow episode plot pretty close, so I'll keep them and add details from other lists.  

The episode title is a lie, for this half anyway - we will see it next week
First off, the title is a little misleading - there's no sign of the eponymous sword this week!
Arthur is trouserless, again - not again, please
"I'm hardly going to look kingly in my undergarments, am I?" - Arthur
“It’s a good job you don’t have anything of importance to keep secret isn’t it!” - Arthur to Merlin

‘Trust me, if there’s one thing I’m good at it’s keeping secrets.’ - maybe even Merlin to Tristan?
Despite all the slow-mo, the battle for Camelot is over swiftly - surely will be great to see
“How did they breach the gate??” - Arthur? - during battle
“Been hiding in the broom cupboard as usual Merlin?” - Arthur to Merlin?, during/before battle
“Arthur, there are too many of them. We can deal with **** ***** later” - your uncle, Merlin/knights?
Agravaine’s treachery is finally exposed by a Knight of Camelot and he pays for it later - Elyan, it's about time
Agravaine’s deception is discovered by *****, who is later tortured. - Elyan
‘I look for her in the room and she’s not there… then I remember why.’ - Elyan about Gwen before discovering treachery
“I’m fine… maybe a broken rib or two” - Arthur?
Arthur undergoes a radical personality change thanks to an enchantment - there was a good theory that it's Merlin who enchants him to force him to leave Camelot to save his life
Merlin has to reluctantly leave an old friend behind - Gwaine?
Merlin is forced to leave someone close to him behind.
“Those that did not escape are either in our dungeons, or dead” - have no idea
‘Arthur would never abandon his people. He’d rather die.’ - Merlin/Morgana about Arthur
Arthur gets a new look…and accent - cool, would love to see
“Burn their crops. Let’s see how they feel when their children begin to starve” - Morgana?
‘Prepare the horses – we’re going on a hunt.’ - Morgana
Elyan is tortured by Morgana - not cool
Morgana likes her snakes. - as torture device?
“With a little persuasion it can cause he can cause a man pain beyond all imagining” - think it fits here
Agravaine’s allegiance to Morgana is explored a little. Is he having doubts? - possibly, she treats him like shit after all

‘I would do anything for you, you know that.’ - Agravaine to Morgana?
Tristan and Isolde are soon indebted to Camelot thanks to some life-saving action - good, nice node to legends

 ‘We prefer to think of it as free trade.’ - TI line definitely
"We're too quick and too smart for the half-wit king in Camelot." - TI again
“I probably should learn to think before I speak, shouldn’t I?” - TI?
‘You and your kind bring nothing but misery to this land.’ - to TI from Arthur? or other way round
Arthur and Merlin switch roles… and Merlin loves it - I'd love it too

“I’m sorry to have been a disappointment Merlin. I’ll try harder in the future” - but not if it's like that, pure Arthur
‘What kind of coward would deny who he is?’ - Arthur objecting to change of clothes?
‘It’s the perfect disguise!’ - Merlin to Arthur, trying to convince him
“Whatever you say, I’m entirely in your hands” - Arthur to Merlin, it's so sad, hope not
“Welcome home Merlin” - Hunith
“******* **** Merlin” - Welcome home Merlin
Arthur finally realises Merlin was right all along - finally
The King begins to wonder just why he's so unpopular. - learns about Agravaine betrayal
"It seems your worst fears have been realised, Merlin." - hope that it's Arthur to Merlin, but not sure
Morgana uses Gwaine for her personal entertainment and he has to fight for more than his life - not going to elaborate
“******, so handsome, so selfless. Of course you shall have some supper, as long as you are prepared to sing for it” - Gwaine
Don't mess with Gwaine - especially when he's tired and hungry.
There’s two happy reunions, but they don’t happen until the end - Arthur/Gwen, Merlin/Hunith
“I missed you” - Merlin to Hunith? or It's Arthur/Gwen moment
There's more than one reunion on the cards!
More than one reunion happens in Ealdor.
No sign of The Great Dragon or baby Aithusa - expected

Arthur is a tree-hugger.
Arthur hugs it out with a new special friend.
"No-one likes to be called fat."
“Are you saying that I’m fat!” - Arthur?

"Sorry Merlin - some of these things are a little on the tight side!" - Arthur to Merlin
“Without me he wouldn’t last a day” - Merlin, I about T - like it much more

Can't place 

‘I was enhancing it for comfort and ease of use.’ - could it be about belt?

“Easy now, we don’t want anymore holes in that belt!”
“That doesn’t explain why I look like a ******* *****!”

“You look like a turniphead!” - Merlin to Arthur?
“Are you suggesting magic?” - but maybe it's enchanting Arthur?
“It must be hard to be so ugly”
