Weft thoughts
Rowan (that's the name Strange calls her by, and she indulges him) would laugh, if she could, when people wonder why she's so picky. What makes her keep to herself for a few decades, and then find a human and go, "Yes, this one is mine; he needs supervision at all times." If you ask her, it should be obvious. But people - even sorcerers - can be surprisingly blind to what's right in front of their noses.
Imagine that you have a great place, a large garden, and many cats to play in it. And that occasionally, a stray will get in pick a fight. Normally, you keep an eye on things, but you don't get in the middle, do you? Yours are better fed, capable, and all you'd get by putting yourself in the way is to be more shredded than you'd like.
But then, when your other cats are distracted for one reason or another, the damn stray is back – and bullying a kitten barely beyond the furball stage. And the kitten, instead of running for cover or trying to get one of his elders, stands his ground with the most reckless attitude you've seen in ages. You can bet that an intervention is in order! And you may decide this dumb, impulsive, adorable kitten needs you to keep an extra eye on him from then on, even while he grows into a sleeker, stronger creature. Character doesn't change, after all.
So she sticks to Strange (literally), because you never know when he'll utilize suicidal stupidity as a legitimate fighting technique. Sure, the Eye of Agamotto is responsible for him never growing better at self-preservation, and she loves and hates the green gem for it. It means her human has another chance (always another) but it also means that he has no incentive to take care of himself, and there's only so far she can help.
And then, almost out of the blue, one day... Oh my God, there's another one! Too smart for his own good, nice facial hair (well, from what she's learned of human standards...and/or Strange getting all dreamy), ready to protect the world any day, and the same disregard for his own safety. As if he didn't count. There are people he's important to! What do these two need, a bullet list?
At least, Strange's new boyfriend (it turns out that always dealing with apocalyptic events does give you a 'seize the day' attitude) is not completely helpless. Rowan can appreciate that he created a red armor for himself – one more way they kind of match. Did Tony decide that following taste? Instinct? Did he know that, all other things being equal, you are more likely to win in red? Not that it really matters. But at least, she doesn't have to stretch herself over both of them. She's not infinite, and one is quite enough to watch over at any given time.
She's happy that her favorite found love, though. He deserves to be happy. They deserve to be happy. At least between one apocalypse-level event and another. Of all the dimensions, they're living in one of the most messed up, that's for sure. Maybe not Dormammu-level awful (not yet, and not if Strange has a say in it... But seriously, who else would think to bore a monster into giving up? Same off-the-chart levels of idiocy and genius), but moments of peace are rare and precious. There's no sense in wasting them alone. They have someone who understands. Because he, too, should probably be under permanent supervision... Tony realizes as much, thankfully. That's the point of all the sundry AIs, robot, assistants (nannies) and mixed creations.
There's also one selfish reason for her to appreciate Strange's boyfriend. She can trust her pet to him. Yes, if anything happens, the two of them might do something cosmically ridiculous and equally dangerous, but at least, now, they'll have each other's back. And their respective teams' support, if they will actually make full use of it. Which means that she can have some extra free time. Not that she needs to catch up with a show or anything of the sort. No, she has a crush of her own.
One that resides in the next universe over, because of course things are never easy. A never-to-be fulfilled love (not unless something dimension-altering happens), because the object of her admiration is an insensate piece of cloth. But oh, what a splendid cloth it is, dark and handsome and heavy with affection, clinging to it both from its owner and his partner. She's not ashamed of her penchant. She's not the first and won't be the last to love art the way you should love a partner. And maybe, some day, the dimension it lies in will change. If there's one thing she's learned, in all her life, is that you never know.
