Leo and Reyna hate each other (well maybe not quite that strong, but they still don't like each other. Plus, they're not gonna interact with each other in BoO, since they're going in complete opposite directions and all. Finally, Leo already has a love interest in Calypso, which would be the most reasonable relationship, and indeed the only non-forced one, in HoO, except for the fact that Calypso is immortal and Leo, sadly, is not. In conclusion, The chance of Leyna is about the same as the chance of Jeyna, which is .00001%.
