A boy appearing at the end of that hallway is curious, since there wasn't a boy at all in that sequence in Empire. All the other visions, in both the film and novel, seem to be actual representations of the events that happened, with Rey's presence being the outlier. That there's no further elaboration other than "a boy" tells me it's just deliberately vague to make the reader fill it in themselves rather than any kind of a hint about anything. A vision of Anakin as a boy seems plausible enough.
This is why I'm speculating that perhaps it's a young Kylo/Ben. He's certainly the only character from TFA we can immediately associate with a "boy" who has any reason to be on Bespin at any point ever. In the end, we have nothing from the OT to link to the appearance of a boy during the Luke/Vader fight, so an OT reference seems like it's out.
It seems to me that, unlike the other scenes in the vision which depict singular events, the Bespin thing may be intended to lace together multiple events that both happened in that same place: the duel between Vader/Luke that resulted in the saber being lost, and Ben looking for the saber (only to fail to find it, or perhaps to have it taken by Maz). I could see something like that being a first step on his path toward his Vader obsession, which flows nicely into that obsession escalating and him joining the Knights of Ren/First Order.
I mean, we already know he hangs onto trinkets of Vader's, and he makes a specific claim on the lightsaber despite there being no certain reason why he should be able to identify it (unless he's encountered it before or was otherwise previously fixated on it).
