Adam and darius provide the following proofs for vertical angles to be equal

Darius proof which is:

angle 1 + angle 4 = 180° (transversal t is a straight line)
angle 1 + angle 2 = 180° (PQ is a straight line segment)
Therefore, angle 1 + angle 2 = angle 1 + angle 4
Hence, angle 2 = angle 4

is CORRECT.
