Jim's not quite sure what he expected to happen, but his eyes widen in surprise at what inevitably does. His sweater is shifting, the fabric unraveling itself and reforming as Sandry bids it - through some kind of telekinetic force, apparently. He's heard some species with higher psi ratings could develop powers of that magnitude, but he'd never seen it himself.

Jim raises his other sleeve when the right one finishes, undisguised fascination overtaking his expression. Sandry finishes her work with a grin that Jim echoes, turning over his arms to look at the handiwork; it's just as stable and neat as it was when she started.

"That's incredible! Where did you learn that?" Jim runs his fingers over the new seam in wonder. Whatever vestiges of hesitation he might have been fighting with before appear to have been erased. "Does it only work on fabric?"
