In the end

[Topstudent]

He was in a coma for a long time, but in the end there was nothing more they could do for him, so we had to let him go.

Hi, teachers. Is this completely natural? Is 'in the end' completely natural here? How is it compared to 'at last' and 'eventually'?

Yes, it's a natural use of the expression. The other options work equally as well. I don't think any of the three options are necessarily any better than the other two. It's just a matter of personal preference as to which you choose.

Hi, teachers. Unnecessary.

I wouldn't use "at last" there.
