I have three questions about the following sentence. Please help.
I thougt that next time I would not (stop to run?) stop running(,?) even when I become (became?) tired.
Next time I will not stop running even when I become tired.
I thought (decided) that next time I would not stop running even when I became tired.
I was not sure about "became". Even now, I don't quite understand it.
In direct speech, I'm talking about something in the future. Right?
Mike: Next time when I become tired, I will not stop running.
Mike said that next time when he become (became) tired, he would not stop running.
In direct speech, "become" is related to the future.
Could anyone please explain how backshift works here?
