Anakin sent back to Siri the impression that he wasn't put out about the misunderstanding. At least not more than was usual for such situations. He had been woken up at 2 am, after all. But beyond that, if it was a 'mistake' is was unintentional and ultimately forgivable.
Not having anything more to add, he slipped back down the outcropping and headed back to the castle.
He did hope Obi-Wan was willing to have an honest discussion about the root of this night time excursion.
