• Bucket Up, All For Luck Merlin didn’t really expect it to take five Knights, two old men, a woman and a horseshoe for his plan to work, but then again the extent of his plan had been more along the lines of an adamant  ‘I’m not in love with Prince Prat (except, really, I am)’ than an actual plan. 
• Burning for Burning "This is what you need to do," Arthur says, and tightens his lips, staring hard at the cabinet behind Merlin.

Arthur, meanwhile, is definitely supposed to be taking over his father's company some day, but instead spends most of his time scowling at Merlin, making lists about him, trying to find excuses to fire him and, most of all, trying to pretend he is totally not head-over-heels for the jumped up little upstart.

They talk through the door and eventually end up falling for each other.
