Well, that's the million-dollar question. Literally, because we're not really sure if our toaster has a million-dollar bill in it somewhere. But let's assume it does.
If you return to present time, our toaster will likely still be there, still working its temporal magic. However, you might notice that it's a bit... different. The buttons might be slightly sticky, the toast might be a few degrees crisper. Don't worry, it's just a temporal glitch.
We recommend you stick around for a bit to see if it sorts itself out. If not, our team will send someone over with a temporal toaster wrench. Or, you know, a toaster-ologist.
