In the first episode of Umbrella Academy('We Only See Each Other at Weddings and Funerals'),Five comes back from the future using a 'temporal anomaly'.
In the process,it is shown that he is aged backwards,leaving him with the physical appearance that was exactly like when he left the Academy
and traveled forward in time.
However,in the second episode('Run Boy Run'), he does not age forward when he travels through the time towards the future.
If he ages backwards when he travels back to the past, then why doesn't he age forward when he travels forward to the future?
Was there any explanation given to this in the TV show(or in the comic)?
