Kai Owen has been interviewed by ScienceFiction.com. During the Q&A he comments on Torchwood’s ever evolving format, and what the future might hold for Rhys and Gwen.

“Personally I think the alien of the week thing was good,” he explained. “I enjoyed the first 2 series, although Children of Earth was probably it at its best. That story arc over five nights was incredible TV. I liked Miracle Day. It did work, but not as good as Series 3. But it’s constantly evolving. If it comes back, it might have a different format again.”

Speaking about what a future series may involve, he said: “I don’t think Rhys should ever become a member of the team. I do like it when he gets a bit of action, like when he and Gwen go on a little mission. I love that, so maybe some more of that…”

He revealed that the series is “all up in the air at the moment”. “Who knows?” he added.
