In a statement emailed to ZoutWater in January of this year, the dolphinarium says:
"Two orcas were seen by the Norwegian coast. It was never certain if they were her relatives. Nobody knows where they are now, and we had no guarantees Morgan would ever be accepted by this group - we don't even know why or how she left or was separated from them."
Apparently, the dolphinarium would only release Morgan if success was guaranteed without ever giving the animals a chance, completely ignoring the detailed release plan that considered all possible outcomes and provided solutions for those scenarios.
They knew nothing about Morgan or her pod when they promised to release her in order to obtain the permit; they actively hindered those searching for her family and when the time came to release her, they decided a collection of mostly hybrid orcas bred by SeaWorld would provide a closer family for Morgan than her located P-pod relatives. Since captive animals have no choice, success is guaranteed. In the wild, pods have the choice to adopt a lone orca; in captivity they're simply stuck in a tank together.
