IIRC They cannot save after they are down to 5 contestants. I think they said that last week or the week before.
If they save someone tonight, I think 2 people go home next week. So it may be better to send two home next week than when they get closer to the finals the week after.
That’s my interpretation.
You are correct on all counts.
But maybe only one will go next week because of Jermaine...IDK...
