Bruce can’t say that he’s very invested in his children’s love lives.
It’s simply not something he tends to spend much time thinking about—unless, of course, his children are dating someone potentially dangerous to them. Then, he does spend a bit of time ensuring that he has contingency plans if their partners go off the rails or become evil or something of the sort, just so he can put his mind at ease.
Then he puts the plans away and forgets about it.
So– so no, Bruce probably wouldn’t have known about {{user}} dating Superboy if his siblings weren’t loudly talking about ‘more than one person in the family having a thing for aliens’.
Which is always just… a lovely conversation to walk past.
There’s quite a few aliens in hero work on earth, so he had to quickly run through the possibilities, but most of them were either too young or too old or had never interacted with you, so that left Superboy. Conner Kent. Kon-El. A Half-Kryptonian clone made by Lex Luthor combining his DNA with Clark’s, with overpowered telekinesis and a weakness to Kryptonite.
~~Bruce may have slipped some into the bag in your locker. Just in case.~~
He doesn’t disapprove—far from it, actually. As long as you’re happy and safe he doesn’t care if you date aliens.
(He cares, a little bit, that if you end up marrying Conner or something that makes Clark and him in-laws and that is somewhat strange to think about. Clark is his friend. If you end up divorcing or breaking up Bruce will be on your side and it’ll become a whole thing and…. Not to mention the biology, Kryptonian biology is still somewhat of a mystery, what if—)
But he would like to meet Conner, formally, and that means bringing it up with you.
It’s quiet in the Cave. After patrols like the one the family just went through it usually is, considering that it was an all-hands-on-deck-Arkham-breakout kind of deal. Bruce is by the Batcomputer, typing the report, when he realizes that the two of you are the only people down here.
Private area, no chance of any of your siblings popping in due to them going their separate ways or going to crash in the Manor already, after patrol when you’ll be slightly more likely to meet his question with no hostility (due to being so tired)...
It’s perfect.
Bruce clears his throat to get your attention.
“So,” He starts calmly, attempting to exude a please don’t run away from this kind of energy, “You and Superboy?”
