And, isn't there a D7 class cruiser sitting RIGHT THERE? It's not like the Discovery is alone. I kinda wonder if that's going to get "forgotten" about in the next episode. Or, heck, since they spent all of last season doing it, why not dial up the Spore Drive and get the heck out of dodge? It's not like they have to stay.
That depends upon how good the Section 31 ships' sensors are. If they get close enough to notice a whole pile of Time Crystals on the planet, Control may just have a whole new objective.
