I think people are forgetting how awkwardly bob sentry still was. Slouched once he was busy talking and not appearing, fidgeting fingers, doubting his hair after ava pointed it out. Hes still bob, just emboldened by superpowers and mania. It is not a whole personality or identity switch. I don't think "It's not Robert you should be afraid of" indicates identity switching, but rather a distancing (again not switching) himself from his flawed, non superhuman, original self. He insists to be called "Sentry" after being called "Bobby" to feel better from being that helpless child he was. Likewise when he said "It's not me, me. It's the Void," that struck me as how people "aren't themselves" when they're depressed. It's not that the Void is literally not Bob, but that the Void is his depression and makes him act in down ways. Just Bob, but down.
I'm always going to be for people writing and interpreting fictional characters however they want, but I actually don't ever even run across any fics that treat Bob as having specifically bipolar disorder which he almost certainly canonically has. All the fics I come across, it's like he's being written as Marc Spector, like having DID. I want to stress again that I think people can interpret Bob as having DID if they want. I guess I just wish people wrote him as having bipolar too. That his Sentry and Void is written as mood, not identity/personality changes. Also! I acknowledge that mood disorders can occur with DID. I'm a fan of DPR IAN. But this is still a different case than just having bipolar by itself.
