Things that require attention.

The Giant Ants were dealt with swiftly and without a problem, exactly as Ramla had envisioned.

Before running into Sam and asking for his help, her visions would always end with her people being devoured by the ant swarm. If they somehow managed to survive the first wave, the second one would finish them, but the likelihood of something else leading to their demise was much hight.

Without the Doctor's and the Valkyries' help averting that future would've been an impossible task, but fortunately they were able to make it, and there was no going back now.

Almost everything from this point onward was uncharted territory.

Before the Olympians attacked the plan was to use the Bifrost to move the survivors of the Sanctuary to Sam's world, but with the portal gate destroyed that had to be scrapped.
