Castiel jumps when he hears the door open. The Angel is supposed to be closed so that he can practice walking, so why is the door even unlocked?! He turns around to reprimand the person, to tell them that they're closed and that they should leave, but his words are stuck in his throat. Standing before him is a behemoth of a man, his dark brown hair falling loosely around his shoulders. The word moose briefly crosses his mind as he ogles the stranger, struggling to remember what he was even going to say.

"Pardon me, are you-" His voice is soft, unlike the one he's become accustomed to hearing every day. And his question, whatever it was, is cut off by that so familiar voice calling out from behind him.

"Sammy! You made it!" Sammy? He looks between them as Dean walks up to him, hugs him and then claps him on the shoulder, his smile lighting up his whole face. He stands there awkwardly, wondering idly if he should excuse himself to go do something else or if he should continue to just stand there. He attempts to excuse himself, but Dean grabs him by the arm and gently tugs, pulling him back, rooting him to the spot. "Stay here and talk with us," he says, his eyes boring into Castiel's and making him feel more than a little awkward. "Besides, Sammy here might be able to help you remember more of your past."

"Um… Yeah." Sam offers, his shoulders lifting in a half shrug as he stands there, feeling just as awkward as Castiel. "I'm Sam by the way," he stretches a hand out, a gentle smile on his face, though he can tell that he's suspicious about something. "I'm assuming then, that you're Castiel? The same one that we spent years with, but can't remember a single day?"

"Yes." Dean grins and steers them both towards a booth, making them sit down and get comfortable before he offers to get them food and drink. He half listens to Sam argue with Dean about salads and eating healthy, still wondering who he is and what his relationship with Dean is. He has his head cocked to the side and he's squinting at him, trying so hard to figure it out, and then it clicks. Sam! Of course! Sam is Sam Winchester, Dean's little brother!

"Finally figure it out?" He's startled by Dean's voice, and nods nervously as he watches him place plates of food down on the table. "Good, 'cause it looked like you were about to fry your brain thinking about it." He smiles and picks at his food as he listens to the brothers talk, wondering how Sam could help him anymore then Dean did.

For the most part he is silent while he eats, though occasionally he answers questions like how he's liking working at The Angel and what he thinks of what Dean has told him about their shared past. He thinks about each the answer to each question carefully, sometimes tilting his head and squinting his eyes a bit as he concentrates, and other times he answers relatively quickly; though in each case, Dean and Sam can tell that each word is chosen carefully, as if he is walking across a frozen lake and afraid that one wrong move will send him right through the ice into the cold water below.

And with every answer that he gives to every question posed to him, Castiel can see Sam's mind calculating, analyzing, thinking about something. Testing him in some way, though he's not sure why. But he hopes more than anything that he makes the pass, because he would really regret having to leave this wonderful place if he didn't. The Angel and its workers and customers, and most of all, Dean, have come to mean home to him, and he would hate to lose them, after working so hard to get them. So please, he silently begs, studying the brothers and listening to their conversation and memorizing their speech patterns, Let me pass your test. I don't know what it is that you're wary of, but please let me stay.
