Andrzej came back home, which did not smell like dinner. This surprised him. Dominik liked cooking a lot, especially since he had someone to do it for, so on days when he was not working outside the home, he always prepared something delicious for his man returning from work. Today, Dominik had no plans outside his home. Dinner should be ready.
The reigning silence and the lack of the appetizing smell coming from the kitchen made Andrzej anxious. Dominik knew how much Andrzej was worried about him, especially after that kidnapping by Werner, so he would have sent him a message if something sudden happened.
Unless the situation was extremely urgent.
Nowicki felt uneasy, but decided not to panic yet. Perhaps Dominik was working in the office and lost track of time, or he fell asleep bored with a boring script.
