T-Rex: When someone accidentally gets sent to the past, they always make sure to write a letter held in trust and delivered to their friends decades later, telling them that they made it alright!

T-Rex: Pretty disappointed this hasn't happened to me yet, you guys!!

T-Rex: MAYBE this letter will still be delivered to me in the future, but I'll be older then! If I'm to do anything about it - if I'm to go back and Save My Friend - I should be getting the letter now, when I'm in my prime!
Dromiceiomimus: Maybe the letter arrives when you're old because if you get it any sooner, you mess up in your rescue attempt and die! Or worse!

T-Rex: Huh! I hadn't thought of that!
Utahraptor: Man, you should!

Utahraptor: The letter probably says "Dear T-Rex, okay, let's try this again. You'll get this when you're 80, let's see if you can come back and save me without stepping on ALL the butterflies this time, alright bitches??"
T-Rex: *gasp*
T-Rex: No friend of MINE would commit a cuss like that to writing!

Narrator: LATER, T-REX TRIES IT AND COMMITS SOME CUSSES TO WRITING!
T-Rex: Nothing bad happened!
T-Rex: I don't understand.
