copy cat

Okay, so i have some riddles i'm trying to solve. I'm in love with The 4400 on USA network, and i was reading Mia's journal. I noticed that in entry 2, 3, and 4 there are random letters that are blue instead of black. So, i wrote them all down and am trying to decode them.

From entry 2:
y-c-p-a-o-t-c
can you figure it out? it actually didnt take me too long. Start with the last letter and move to front, only picking every other letter: c-o-p-y. Then, the remaining are c-a-t. And interestingly enough, the show AFTER that was about a copy cat person, pretending to be someone else. See, its a clue as to whats coming in the next episode.

So, here's the rest...
entry 3:
T-o-f-b-c-e-t-u-u-a-t-r-h-K-e
There might be something significant in the fact that T and K are capitalized... or it may not be anything. in the previous one, c wasnt capitalized and it was the first letter.
The show after this entry is about Mia and other kids being kidnapped by people from the future, and then Mia is sent back in time. She is erased from everyone's memory.

Entry 4:
e-e-h-o-e-e-e-n-h-d-P-t-h-p-o-l-v-s-l-o
The reason i want to figure this out is b/c i havent seen the episode after this yet. So, i want a clue! Hopefully if i can figure out some system of decoding, i'll be able to figure it out!

Any help please???
