About Liam's age: The actor who plays him is 30. If we assume that Liam was, let's say, 8 years old when his father was killed, and then we have the 28 years between "Swan Song" and "Dark Waters" (Liam didn't age after he traveled to the LUS), then Liam's biological age would be 35. I think it is easiest to assume that he simply looks younger than he actually is - some people do look younger than they really are.
