Once Jen met her, Sashia asked Maui to help Jen hold the egg before she gave the egg to Jen. Almost immediately, something in the air would change as Sashia said "This egg is about to hatch, this is a female Riolu egg and according to Mike, she should have inherited the moves Aura Sphere and Meateor mash from her parents". Sashia smiled as she let go of the egg making sure it was nestled in Jen arms with Maui helping her as she said "It might not activate first until she hatches, but you might be able to "see" a blue shape taking the form of me or a tree. If Not, it will appear as the egg hatches which should be quite soon"
