Disclaimer: If you haven't seen the the movies yet I suggest not to continue reading as there might be a minor spoiler within my question.
So we are revealed in the course of the two movies that Dylan's father was performing a Houdini's escape alike trick of getting out of what looked like a safe submerged into water. We are also shown in Now You See Me 2 that he did not make it out of the safe in time and died.
Have I missed it or was there any explanation of what really went wrong and why did Dylan's father fail to get out of the safe? This really bothers me as we are shown how Dylan without much practice was able to open the same safe.
