Rogue squints at the brightness of the soldering but doesn't look away. There's something... off. Maybe it's the way he's speaking, so calm and collected, or the way he stays so focused on his work, not looking at her. Maybe it's all in her head, but—

"Not just for me," she points out, tilting her head a bit to the side. "Unless I weigh you down a whole lot more than I realized, it'd take the same time for you to get there without me."

And there is another worry, deep and icy cold in her chest. One day, he'll decide that it would be easier without her tagging along. Better. He'll leave her behind and she'll be truly on her own in this world that isn't hers and where she has no one else to turn to.

Now isn't the time for those thoughts though, so she pushes through with another (slightly shakier) smile, "I'll get some books. We can read on the way."
