Severus, she thought with a smile as she returned to her office after giving Ron a huge hug and promising to visit soon. How he had gone in her mind from Professor Snape to Mr. Snape to Master to Severus was almost bewildering to consider. At the same time, she couldn't help but be grateful for their relationship. While she was overwhelmed with joy for her friends and their adventures as parents, she had no intention of going down that road and was beyond thrilled that Severus seemed similarly disinclined to domesticity. Then again, their relationship was domestic in many ways... they enjoyed meals together, cooked, read or studied in quiet companionship... They practically lived together at this point, and if you ignored the somewhat unconventional aspects of their sex life, their relationship was not entirely unlike the classic image of a couple who had been together for years, for all the ease they felt in each other’s company. She felt that they knew each other well. Was that born of trust? Or simply fortunate compatibility?
