The other person's.whose time will be dilated?

In which frame?

In both the frames. Could it be that both frames have time dilated with respect to each other? How does time dilation make sense that way?

The other person's.

What will happen if Alice and Bob compare their clocks? Alice's clock will be faster than Bob's or the other way? If both show the same time - where is the dilation?

The only way for them to directly compare their clocks is for one or both of them to turn around and join the other. That changes everything. (Look up the 'twin paradox'.)What will happen if Alice and Bob compare their clocks? Alice's clock will be faster than Bob's or the other way? If both show the same time - where is the dilation?

But the important point is that between inertial frames the relativistic effects (time dilation, length contraction) are completely symmetric. To ask which clock is

That is, Alice, observing Bob's clock as he goes whizzing past her, sees Bob's clock as running slower then hers. Bob, observing Alice's clock as she goes whizzing past him, sees her clock as running slower than his. That is what "time dilation"

Yes.Could it be that both frames have time dilated with respect to each other?

Because it is relative, as HallsOfIvy mentioned.How does time dilation make sense that way?
