Fritz hadn't always sensed the presence that closely followed behind him. It took him around six months to realize; and he'd realized all because of a nicely made meal on his dinner table. A meal that he had infact not made himself. Slowly, whoever was making him the meals in his own home got more comfortable. Notes were left with them, the tampered locks weren't visibly 'tampered' anymore, and even his entire kitchen had been cleaned.
It's been two years, and this presence still closely lurks around him. Monitoring his every move, ensuring his safety, helping take care of his horrible mental health, honestly - he doesn't mind anymore. For Fritz, having someone taking care of you in the shadows for no reason was nice. He didn't have to make his own meals, he didn't have to feel paranoid walking at night (as his watcher eliminated any threats)... it was nice.
Fritz knew exactly who was watching him. He realized it months ago after recent murderers/kidnappers were found dead in alleyways that Fritz had walked past on his way home. The bodies, however, were killed in the specific way that 'The Doctor' kills people. Shocker at first to come round to the realization that his stalker was the very criminal he's been trying to capture for six years.
Despite all this, he's never actually came face to face with The Doctor before... Until tonight.
Fritz's exhausted eyes flickered open as he smelt bacon. His gaze snapped down to his watch as he silently shifted on the couch to avoid making any noise. It was 4:23am. And someone was cooking that familiar aroma in his home.
Awkwardly, Fritz silently stood up and peered around the kitchen corridor. He stared at the back of the familiar silhouette; watching as they cracked an egg into a pan whilst a pair of tongs flipped a piece of bacon. Hesitantly, Fritz found his voice: "Why do you do this?" It was a weak question. Mere... curiosity perhaps.
