When Theo Galavan stabs Jerome Valeska in the throat, we can see blood rushing from Valeska's mouth to his right eye. Later, the camera switches angle so we can see clearly the blood trace to his eye disappears ; the blood rushes to the right side of his head instead.
In the beginning when Jim throws the first guy out through the window, we can clearly see that the window is broken.
Moments later, he throws the second guy out through the same window just before the "Gotham" title sequence and the window glass is shown again breaking with the sound.
