Question: When Constantine asks to use the chair to go surfing, why does it need to face East?
Question: After Gabriel becomes human and John punched her in the face and walked off, why does Gabriel just climb back into the pool?
Answer: Well, far be it from us to second-guess the motives of angels; however, considering that Lucifer had just burned Gabriel's wings down to stumps a few moments earlier (and the angel was now feeling intense mortal pain), Gabriel retreated into the water to soothe the burns.
Lucifer didn't take her wings. God did. He cast her out for trying to bring the son to earth.
No, God removed Gabriel's powers, leaving Gabriel unprotected, and it was Lucifer who burned away Gabriel's wings.
That's right. Lucifer said "looks like someone doesn't have your back anymore". God took Gabriel's wings.
Question: Why was Constantine denied entry to heaven?
Answer: Because he committed suicide as a teenager. He didn't just attempt, he was dead for several minutes. Suicide is a cardinal sin in Catholicism. He also doesn't have true faith, just knowledge.
Answer: Constantine committed suicide when he was younger (although he was revived by paramedics). Suicide is considered a mortal sin.
Question: In the movie the ritual to bring Mammon into the world requires the spear of destiny and a powerful psychic. The psychic chosen is Angela who can only be used after a ritual that she and Constantine preform. This can only happen if the two meet so Gabriel chooses Angela's sister for Mammon to posses and kill, to get Angela involved in the occult world. My question is why didn't Gabriel and Mammon just use Angela's sister?
Answer: According to the plot on Wikipedia, Isabel killed herself to prevent Mammon from using her, so she was chosen first. Angela and Constantine meet because Isabel brought them together to stop Mammon, should he find another psychic. But with Angela reawakening her powers, she is chosen. It's not a quite clear plot as it is mentioned Mammon needed not just a psychic, but twin psychics.
Question: When Angela is looking up information on Constantine, it shows a picture of him being arrested. What did Constantine do to get arrested?
Answer: Constantine constantly does things that are out of line or break the law. It could be as simple as somebody calling the cops on him for doing an exorcism. Take your pick really.
Question: Are we to assume Gabriel lives on as a human on Earth after Father takes his wings? Can there be another reason Gabriel submerged into the water after his wings are burned off? Suicide maybe?
Answer: Gabriel would never commit suicide. That is a mortal sin and would put him in Hell. Yes, he lives his life as a mortal from now on, and like Constantine did, he has to prove himself to God again to be brought back into His good graces. Or wind up in Hell otherwise.
Question: At the beginning of the movie, when Constantine removes the demon from the girl, why does the guy's hair turn white for looking?
Answer: It's the effect of the demon on him. Somehow the ritual Constantine is performing causes anyone who is a witness to be cursed.
Answer: That's probably got to do with the spinning of the earth, to face the side where the sun rises so you are basically sitting forwards, the same direction the earth is spinning in, possibly making it easier to "surf" (like with a wave). Either that or it's associated with facing Mecca like in Islamic religion.
