Soren squandered more than thirty minutes standing on the doorsteps of Zale's bedroom, unsure whether to enter or cowardly push his desire to see him away and retreat to his room.
He finally steps out of his discomfort and gently places his still trembling hand on the lock, after so much conflict with his heart and conscience.
Zale never locks his room from the inside because he expects Soren to show up every night to check on him while he sleeps peacefully.
Soren twists the lock and it clicks open. In fright, he swallowed hard, tripping over his rapid breaths. Shilister's words had stuffed his insides with tremendous hatred feelings. He was reminded of his tragic past, which he was able to deal with reasonably well until now.
