No, not fetus in fetu. That's not necessarily fatal and that's when the fetus becomes a parasite to its living twin. The twin can survive with the non-viable twin inside them for years and years if it doesn't disrupt their vital organs or take up too much of their blood supply. There have been a few documentaries about fetus in fetu. Pretty creepy stuff.
