At the start of Jon Lewis's run, it was highlighted that another thing that sets Tim apart from the others is that he's the sane one. He lost his mother and nearly lost his father (this was before Identity Crisis), but he didn't obsess over it: he grieved as a normal person would, then moved on with his life. It's part of why he considered “Robin” to be a temporary gig, whereas Bruce and even Dick were (borderline?) obsessive about being Batman and Nightwing (Bruce moreso than Dick; but still…) Tim still had a relatively normal family life, with a living father, a girlfriend, some high school pals, and so on. Even in the superhero community, he was hanging out as Young Justice, which was basically a close circle of high school agreed superheroes who liked spending time together.
Then Didio took over; and in very rapid succession, Young Justice was disbanded; Stephanie died; his dad died; his two best friends (Conner and Bart) died; he went all obsessive about being Robin; and his high school friends drifted away. And nearly everything that differentiated Tim from the rest got wiped away.
That's why I think this new Bernard thing might hopefully lead to a restoration of Tim having a normal life. He needs to go back to being the sane one. Though, frankly, he's sharing that with Babs and Stephanie. Still, there are enough ways that he is different from them already that that won't really matter.
