Imagine that Robert tries dating someone—he really likes them or he wants to know what it’s like or they asked and he was like “fuck it, sure.” And let’s go ahead and say they’re not affiliated with SDN. Hero, civilian, what have you
That relationship will not last. Even if we all say that no one—absolutely no one—on the Z-Team has the hots for him or a small crush, they barely understand privacy. They don’t trust whoever Robert is dating. They won’t be nice by any metric to the person, giving this new person—who may well be normal—as much shit as they give anyone else
And while Robert will tell/threaten them into knocking it off, A LOT of his attention will still be devoted to them. Need someone sober to pick them up? Need help calming bat-monster down? Having tech problems? Feeling down and need some Beef (read: Beef and Robert) cuddles? Don’t understand this human thing and now you’re about to get arrested? He’s there. Complaining and lecturing, yes, but there
And this without factoring in the Mecha Man side of it
I’m not saying it’s not possible. It totally is. Z-Team can change, and Robert can reorganize his priorities. I’m just saying dating Robert is either having literal supervillains as competition or ten stepkids who all do not like you and will make sure you’re aware of that fact
