Superboy arrived in costume. Mostly because he'd run into some trouble just before it was time to make it to New York, and the nice clothes he'd chosen to wear were ruined. Luckily, though, he brought some of Ma Kent's famous apple pies. Conner liked Thanksgiving. It was the one time you got to eat everything and no one judged you because everyone was stuffing their face with yummy food. Plus, the pie. He loved the pie. All kinds of pie, too. He knew Kate was handling most of the stuff, but... Well, Ma Kent said it was good manners to bring stuff. So, he brought stuff. Thank God for his telekinetic powers otherwise he was fairly certain that the pie would not have made it in one piece.
Assuming, of course, that Conner didn't eat it for a pick me up. Luckily, he managed to restrain himself. Ma would be proud.
He knew that Kara was coming with Bart, so he made the journey on his own. It helped when you could fly! When he arrived, Kate had needed help with things. Ever the helpful guy, Conner did what he was told lest it meant no pie or turkey for him. When he saw Teddy, he didn't feel so awkward about being in costume (even if he had a total legitimate reason for why). Eventually, someone knocked on the door and Conner waited to see if anyone was going to answer it. When no one moved, Conner frowned and decided to play door greeter, smirking only slightly when Kara spoke.
"Sorry for the wait. People got kinda busy," he said as a greeting when he opened the door.
