Some lessons here:

1) don't Flash things when abroad
2) don't Flash things you don't know how to revert
3) always take a Nandroid backup before flashing something.

You can fastboot flash the stock boot.img from a computer. There may also be flashable zips around.

In fact, if you download flashify from play, you can flash the stock boot.img without a computer

You can either dirty flash the stock Rom through recovery or search for a standalone stock kernel in these threads that you can also flash through recovery.

Wink You need to fastboot flash stock system.img and boot.img

Franco modifies some system files as well as replacing the boot.img. Just flashing boot.img is not just enough to return to the stock kernel - Source

You need to fastboot flash both system.img and boot.img from the Google Stock Image

But before doing any of this, be sure to make an Nandroid Backup - Its good practice to make Nandroid backups before flashing anything or making any radical changes. Then you can revert back without having any panic attacks.

Although the modifications won't affect the stock kernel whilst he is abroad, you're right - if he wants to use other kernels once he has returned home, he'll need to flash a rom first

By fastbooting system.img and boot.img, if I have an unlocked bootloader, will that get locked and will I lose root? Will I lose my desktops and icons I have setup? (If so, is there any way to save those?)

Also, I have a TWRP backup; good enough?

Soon as you open up the bootloader you should do a backup and an efs backup which should be stored off phone. I love the new TWR app which allows for backup to usb thumb drives. Plus you can back up with out going into recovery!
