Jason felt like they were forgetting to tell Damian something, that they were sending him into the mouth of the hellhole that was Gotham City without all the information. He didn't think it was a small thing either, he felt like it was something big, something that could make or break Damian's chances of success integrating with the Bats.Talia told him he worried too much, told him they had covered everything, that even if they hadn't it would be fine because Damian was skilled at adapting to new information. She told him to focus on his studies, on getting the degree he'd always dreamed of. He'd worked hard to get into Oxford's English Language and Literature Program, after all, he should not waste the opportunity by being too focused on worry for his brother. She even killed the clown to put his mind at ease, so that Damian wouldn't be in the same city as his murderer.He and his mom had covered everything. He had to trust that.Damian, meanwhile, happens to be missing the key information that Jason is supposed to be dead.
