There's a lot of projecting here, from all sides. Strange can't help but look a little confused at Lambert's 'afraid of change' remark. Sure that might be it. Or maybe she's just possessive? Isn't that the simple answer?

"There is a way for the two of you to get to know each other better and work through this," Strange idly remarks, as he looks over at Steven. He turns his attention back to the Rose Queen. "If you come with us, there will be plenty of time to talk in the Wyldlands."

And instantly after he says this, Strange just mentally prepares himself for the rest of the carnival to try and shoot him down. But he's not looking in their direction: his attention is focused squarely on the Rose Queen.
