This is pretty interesting. As for the nanites malfunctioning, I think I came up with a sort of cool plot to avoid that problem. I'll try and post that soon, but if you want to beta read it for me, I'd be fine with that.

great start

Yikes! Rex needs to be less clumsy for sure! Love your fics here! Everyone loves a good Rex whump. Thanks for sharing your stories and keep up the good work!

Aww, poor Rex. I'm somewhat in the same position, but at least not to this extent! I bet when Noah finds out (probably from Rex telling him) he'll feel kind of guilty for not being there for his best friend. Anyways, great chapter!

nice job, great chapter!

Glad to see you are still here and writing about Rex. This seems very realistic. Nice.

These oneshots are really well written. Keep up the good work!

Good history, keep up the good work :)

I am sorry but this was so cute. When the Spanish popped up I seriously couldn't handle it, I kind of fangirled. You are an amazing writer and given the circumstance that the show came out so many years ago and you are still writing about it is awesome. I am also writing one. But different. I look forward to more.

Ah yay, I'm so happy to find out you updated! I really enjoyed this chapter, and can't wait for more!

I love it! Thanks for trying not to swear too. Ive hot a two swear Max before I stop. Your characters are perfect!

That was so sweet. I really think that Holiday is like a mom to Rex. We need more family fluff along with Rex whump.

Cool stories. You are right that no one writes stories like this about Rex and I think that people should write more of them because they are awesome

The ending was cute. I like the idea of Holiday singing Rex to sleep. For future reference you can try this Spanish lullaby:
Arrorró mi niño
arrorró mi amor
arrorró pedazo de mi corazón
este niño lindo
que nació de día
quiere que lo lleve a la dulcería
este niño lindo
que nació de noche
quiere que lo lleve a pasear en coche
Duérmete mi niño
duérmete pedazo de mi corazón
Hush, my child
hush, my love
hush, piece of my heart
this pretty child
which was born at daytime
wants me to take him to the candy shop
this pretty child
which was born at night
wants me to take him out for a ride in car
sleep, my child
sleep, piece of my heart.

That was great! Can you involve Cesar too? I would like to see him care for his brother please! Please update soon!
