Duo Control, Duo Rescue
A working Ron means two effective wands trained on Lockhart; the boys can bind, disarm, or stun him rather than rely on a single wand and a bluff. Lockhart’s dueling ineptitude—telegraphed at the Dueling Club and in his office—makes it far harder for him to steal initiative against two armed students. Without a backfire there is no forced cave‑in, so the party stays intact and reaches the Chamber together with Lockhart secured. Harry still provides the Parseltongue key and the loyalty that summ
- Lockhart is humiliated by Snape at the Dueling Club and is easily disarmed by Harry (CoS).
- In canon Ron’s broken wand limited his combat utility; with it whole, he can restrain Lockhart alongside Harry.
- The tunnel collapse is caused by the broken wand’s backfire; remove it and the enforced separation disappears (CoS).
- Fawkes responds to Harry’s loyalty to Dumbledore, and the sword appears to a worthy Gryffindor in need (CoS; DH clarifications).
