Ron cringed when she said that name - it did nothing at all to improve his mood. "I'm not being daft, I'm being careful! Even if he really does want to help you," a concession he was only making for the sake of argument, "Do you really trust him not to get - followed, or caught out, or something? I mean, we all saw plenty of him fourth year, and he had a bit more in the way of brawn than brains, didn't he?" He was almost unthinkingly determined not to accept help from Krum - it hardly mattered to him which excuse he chose.
