Melinda got a glass in the kitchen and filled it, then just placed her hands on the counter and took a few deep breaths. He scared the shit out of her when he did this, and she'd meant what she said. Someday, she wouldn't know, or she'd be busy, or she just wouldn't get to him in time, and he could die. She wished he'd do more to be safe or just do something safer. But she wasn't stupid enough to think that this accident would do any more to change his mind about his career than any one of the others he'd had.
After one last deep breath, she picked up the glass and brought it up to him, handing it to him. "Do you want me to go put away what you were working on so it doesn't explode or spoil or something. Don't give me any nonsense about it not being safe," she said, holding up one finger to pre-empt him. "My NEWT in potions was just as high as yours, I can handle one cauldron."
