The Pokémon Rescue squad has some links towards the rescue team International Rescue of the famous Thunderbirds series:
They both are rescue teams that help those who need it
While the sons go on their missions, the father stays behind and leads
The leader's (and father's) name is Jeff
One of the sons are called Virgil
Virgil's Eevee is confirmed Female when he said this Eevee is a girl.
This is the second time Ash looked up Umbreon on the Pokedex since BW004: The Battle Club and Tepig's Choice!, when Ash is mistaken Tepig as an Umbreon due to its covered dirt and thinness when its abandoned by Shamus. For now, he meets a real one.
