in the movie keanu reeves/ john constantine has two tattos on his arm when put together they make some kind of symbol something from the acult. but anyway through out the movie these two tattos are on the inside of his arm but when he finally puts them together the image is on the outside of his arms!
No the tattoo goes around his arm, so he has the full symbol on both his arms wrapping around. and then when he puts his arms together it shows half of each tatto forming the full thing again.
