Life seemed to settle down when Severus got back from Italy, he moved into the cottage without complaint and he apparated to Edinburgh twice a week to keep up with the trial data which he brought home to analyse. When he was at home he also researched alternatives to wormwood and lacewing flies, he needed something which would retain the properties of the potion without risk to a foetus. It was not an easy task so many things were untested and therefore too risky. He also spent time compiling his book of potions for omegas. He had even found a publisher who was interested in his idea.
