What the Potion Master had considered childish arrogance, had been nothing but desperation. Now, he regretted the harsh words and thoughts he had offered over the years. It helped that the young man did not look like a carbon copy of his father any longer. No glasses, haircut and wardrobe, and more confidence - without appearing arrogant - helped Severus separate tormenting memory from the here and now. Still, a part of him advised caution of this "new" Potter. That it was only sensible to maintain an emotional distance because the young man had far too much power over him already. He had no control in their relationship, and the fact that he had come to enjoy Harry's visits had him on edge.
