To date, the only male the calf has been introduced to is Makani, so it definitely wouldn't be Ulises. Who you saw was probably Kasatka, Makani and Kalias mother.
As it stands, the calf has been introduced to all the females, so Kasatka, Shouka, Orkid, and Corky, as well as Makani.
AFAIK, she hasn't been introduced to any of the males (aside from Makani), however I imagine that the next whale to be introduced will be Nakai (its honestly rather strange he hasn't been introduced yet, as he was with Makani by the time he was 9 days old), followed by Keet, followed by Ikaika, followed by Ulises.
