She outstretched her arm. "Put your arm around my waist," she said in an entirely business-like manner. If he looked too weak to hold onto her, she'd sling him over her shoulder instead. (She's carried her two sisters, she can probably carry one musical star.) Provided he did not completely object, she would hold onto him and have the reinforced familiar carry them away from the scene.
