´Tom or Lily
Why should Tom or Lily have been the student? The instructions how to brew a perfect potion are found in Snape's book. Nothing suggests it was Tom or Lily. --Rodolphus 16:18, August 26, 2010 (UTC)
- Because they are known to be extremely talented students at Potions.

Also, if it had been Lily, knowing how much Horace admired her, after Harry won it, you would have thought that he would have commented on her son being the only other student to achieve this. --BachLynn(Accio!) 20:39, February 17, 2011 (UTC)
