Some things happened in 4x02, but really, the important thing was Arthur's face. Mainly Arthur's face in relation to Merlin. So here, have some pictures of Arthur's face from the episode. (With spoilers.)
Full of distress, while Leon plays Sir Cold Hard Logic. (I do not envy him this role, not when Arthur's looking like this.)
Saying goodbye to Merlin, who doesn't want to leave. Augh, boys.
Watching Lancelot and Merlin leave. Someone with gif-making capabilities needs to have at this moment, because in addition to the general devastation, Bradley gets some wonderful rapid blinking in there, of the shut-up-I-just-have-something-in-my-eye variety. ♥
Lancelot: BAD NEWS
LOL J/K MERLIN'S FINE
Look at him, he can't even roll his eyes or snark at Gwaine or anything, he's just so happy. (Also, hooray Merlin/Gwaine hug!)
Their little grinning faces, oh my heart. ♥
And groping, gotta have some groping.
More grinning. This could totally be the prelude to kissing each other senseless, yep. It's got that perfect mix of intensity and joy.

And some more groping.

Oh Arthur, could you look any more besotted? I don't think you could. Feel free to prove me wrong as often as you like, though.
Bonus!
One more face, from 4x01, because it's just such a wonderfully gentle, concerned look. He really does seem to have grown up a lot since last year.
