Xena arrives to a tavern and tells Joxer that Gabrielle is alive, but we had already seen a scene where Xena told Joxer the same, next to the hole Gabrielle had fallen through, in season four episode "A Family Affair".
Ares says he's going to tell his parents, Zeus and Hera, about his upcoming wedding with Xena. However, by the time this scene was chronologically set (Season Four), Hera was trapped in Tartarus (which happened in a previous "Hercules" episode) and she didn't come back until the "Hercules" series finale, which took place during Season Five of "Xena".
Ares says the reason he supposedly saved Hope was because Gabrielle asked him. However, in season four episode "A Family Affair", which takes place chronologically after that scene, Gabrielle believes Hope is dead and she's horrified to discover she is still alive.
Ares tells Xena that he saved Hope from the lava pit (from the episode "Sacrifice II"). However, in season four episode "A Family Affair", which takes place chronologically after this flashback scene, Xena doesn't know that Hope is alive. Furthermore, in "A Family Affair" Hope reveals that she was saved by Dahak, not by Ares.
