New Person, Same Old Mistakes.
It was what every person, partner thought of Sasuke currently, since he left the village he had changed, and too much. Of course, only physically. Mentally he was still the same, a dark vision, clouded by revenge and with goals for a future that looked terrifying to anyone's eyes, except his own. He was still selfish, he was still impulsive, so many bad things had to be said about him, but it would take too long.
You and Orochimaru were student and teacher, you were another of his perfect students, you were at almost the same level as the Uchiha, so the Ex Sannin did not have the best idea than to send you together to a mission. But of course, he never thought about how you would get along or how each of you would behave.
