Truth was? Dean was a demon trying to impregnate Cordelia with his Hellspawn.
He was just holding that card up his sleeve until after he got Cordy into bed, which would prove to be a while with Dean's new epiphany when it came to the budding relationship with the seer. For once in his life, he was as relaxed as some retarded beach bum who was toasted over what he thought he would be. He dared not think of meeting the great and powerful Angel not because he didn't want to be judged but because he was afraid of what he might start to become suspicious of. Dean was told to watch his back when it came to his girlfriend's special buddy by everyone in the firm and he didn't want to exactly stretch that any further than it actually was.
His idea of a 'real date' with Cordy was different from his idea with a 'real date' with anyone else to the point where he didn't dress up like a redneck but still sported his trademark leather coat that made him feel more confident. That made him feel more like his father in most ways as he tried to use it as a shield when it came to some of the things he had to deal with in life. He didn't think he would have to use it when it came to a date with Cordelia but he did want to make an impression. His affections, after all, did run deeper than some lay he was going to get for the week before brushing her off. It was something he couldn't see himself doing anytime soon.
Just as he couldn't see himself going on another date and trying, so hard to be a good 'boyfriend' from opening doors to not drooling over the waitress's legs that he did notice at the corner of his eye. But it was all about Cordelia even though she did have to kick him under the table when he ogled back at the young woman who seemed enamored by Cordy's own white knight. He'd blocked out the conversation of his choice in music saying he'd left the Alanis CD in his house ( that he still wanted Cordy to come see ). He didn't exactly run in fear of Cordy's music, in fact, he was looking forward to blending both of their music together under his passenger seat even though he knew his brother would think he was possessed...and as would he.
By the "end" of their date, Dean wanted to hang himself. He preferred it when he did see his other girl beaten and wanted to steal the security tapes of the parking lot so he could track down the bastard and rip him to pieces. He got no such thing and promised, silently, that he would return for her without the "other" woman. He felt dirty as he walked around stained in their dinner but he said nothing and only listened to Cordelia during the duration of them walking it. He did want to scream or tell her he couldn't go to Angel's. But he didn't want to push anything from their 'coupling'. He did like her. More than Cassie and any other female that had crossed into his life.
He was just scared for her. "Did you do something to seriously piss the fates off?!" He may just have as he looked for cover but only found the shelter of a newspaper that he held over Cordelia's head and continued looking as miserable as he did when he saw the Impala after dinner. His hair stuck down and spiked. "I have no clue. I did trip of some voodoo bitch's shoe once. She musta cursed every date I would have." Or it was just the stuff he was doing with Wolfram & Hart. If he would a superstitious man he would have been worried but he wasn't. He glanced down at her heels for a moment before shaking out his hair and moving to stand in front of her only after wrapping his leather jacket around her shoulders; bending over by the knees.
"Climb aboard!" He laughed, imagining the sight to anyone else in the world before looking over his shoulder. "Ya'know I ain't that young anymore Cordy. Hurry up before I get stuck like this and you have to give me a piggy back ride over to Angel's." He winked, smiling lighting his face. He could at least try when it came to helping her out for the most part.
