This conversation's going to last for a while, isn't it. So, Strange sits down on the sand, next to Steven. He props himself up on his elbows as he sticks his feet out.

It would just be so easy to explain this away with 'sorry Steven, I'm a terrible person, I know that about myself and hope you now know the same'...except Strange knows that there'll be more questions and justifications and that won't end up well at all. So, Strange pauses for a moment, thinking things over as he tries to find a way to explain this.

"I'm not good at thinking things through—Arabella reminded me of that almost every conversation we had." His tone softens a bit at just the thought of his wife before going back to the tentative tone it was before. "I'm especially not good at thinking things through once I've set my mind on something. And Nightshade..."

Well. That's a whole different set of issues. It's Strange's turn to hesitate as he grapples with his words, eventually settling on: "I thought CY-Ren fighting Nightshade was the best solution."

Is that explanation any good? He's not entirely certain it is. But hell, it's what Strange is going with. "Though what do you mean 'whenever something happens?'"
