Nit: Harry correctly guessing before this chapter that the resonance affects mainly the caster in proportion to the caster’s strength seems overly specific. His experience did indicate that the resonance was a greater threat to V than to himself, so his actions were justified, but his prediction should have been more disjunctive: Either the resonance mainly affects the caster in proportion to the caster’s strength, or it affects both parties in proportion to their strength, or it mainly affects V regardless of who casts what due to some asymmetry, or it affects the caster in proportion to the spell’s magical strength, or something else.

Agreed. This result wasn’t my first guess about the nature of it. I’d assumed that it probably affected V most strongly regardless.
