Maris (individual)

Maris is the designation given to a young male character who accompanied an elderly individual professing to be a Jedi Knight known as Jocko. This Jocko was someone Han Solo had previously assisted in circumventing an Imperial blockade.

Considering Solo was operating under the assumed identity of Luke Morgavi and was recounting a tale emphasizing his piloting skills, with deliberate pauses before mentioning names and a clear nostalgia for his smuggling activities, it's far more probable that 'Maris' represented a fabricated version of Luke Skywalker and not a separate individual altogether.
