Considering that we pretty much got The Doctor circa. Tennant’s time as the Madman in a Box, I’d say they’re probably good
When is falling out of a time machine in motion fatal? It’s one of the most fakeout death setups of all time. We didn’t see them burn up in the damn atmosphere like some of the Lost Light crew in MTMTE #2.
Yes that's true, but Beta also mentioned a while back a few issues ago that the Time Vortex kills people. So it's either they're dead, or they're just displaced in time and Beta and the others need to go rescue them.
That particular group was seen way back in Transmutate's first dream of the future, with the injuries they received here. My guess is they survived.
Think of it from a writer’s perspective. Do you really thinks it’s a good move having Lightbright accidentally kill her friends after all the trauma she experienced in the span of probably five minutes in-universe? That’s unnecessary cruelity the likes of Frank Miller and James Roberts would lose their minds over. Captain Jack also sends his regards.
I'm getting the feeling their mysterious visitors may be some of their team mates that had fallen out of the ship during the time and space travel which by the way I'm surprised they didn't noticed some of their teammates are missing right now.
