Has Delsi and Vilka ever meet?
Yeah! It was actually kind of awkward, their first meeting… they were in space, as Vilka was giving Blake an introductory tour of the Voyager (V’rov homeworld)…
She wanted to take him to see a harem, just for fun — but when they got there they found it had been repurposed into a shared living space for… brood mothers…
Delsi, who was living there, came up and introduced herself, and said she was carrying their brood — as in, Blake and Vilka’s. This came as a bit of a surprise to Blake: he remembered giving the V’rov authorities his “genetic material” for use in their breakthrough breeding program, but somehow he never thought he’d meet one of the surrogates who’d be carrying his children.
Those three became fast friends after that, even though Delsi can be a bit awkward. Honestly the three of them are more like friends-with-benefits… and Delsi eventually moves to earth with them, becoming a permanent part of their lives.
Delsi is honestly a lot closer to Blake than she is to Vilka… but the two V’rov do have a kinship based on being the same species and sharing a culture… and both having to adjust to an unfamiliar world.
