Sam could remember the first time Castiel went on an airplane all too well. Cas was scared shitless, ever since Cas fell from heaven he had gained a major fear of falling, (refusing to go near the edge of a balcony, or even cross a bridge if it was too high), but he would never admit it to either one of them, instead he would use flimsy lies as an excuse to stay on solid ground. Castiel didn't like to be seen as weak, especially in the eyes of the Winchesters; but nearing the check in gates he went into full on panic mode. He had decided he had to get out there and then, "No way was he getting on that airplane" he kept on repeating, muttering to him self in slightly crazed ramblings. He freaked put completely, gaining them strange looks from passerby's, which they soon regretted after being met with one of Dean's famous death stares.
Finally after a long hour of calming Castiel down (and a lot if alcohol) the boys had convinced him to come on the plane. Castiel immediately took the seat closest to Dean's side, gaining Sam an apologetic look from Dean (not that he looked all to sorry) when Sam had to sit two rows back, between a guy who snored and a baby who wouldn't stop crying. When Castiel got on the plane he was okay for a while, sitting next to Dean smiling, whilst Dean chatted away animatedly; but when the plane started moving he freaked out again, bigger, and more panicky this time (if that was even possible). What surprised Sam the most was the way Dean reacted, he wasn't that least bit scared, (well if he is he isn't showing it) even though he also had a crippling fear of flying, that stemmed way back into his childhood, a fact Sam didn't come to know about until later in life, something that still annoyed him to this day. Instead he was as steady as a rock, sitting next to Cas and calming him down, he murmured something to him, too low for Sam to hear and Cas instantly relaxed. Sitting back down in his chair and taking hold of Dean's hand gripping it tight. In louder tones Dean promised Cas it was going to be okay, making the virtually nonexistent personal space between them all but gone as Dean instincivly moved closer to Cas. That was all Sam could see as a really tall person blocked his field of vision, but If Sam listened closely he could swear he could hear Dean humming Metallica to Cas, and Cas softly singing the words back to Dean.
