There are 8 of them! I want their heads!

Question

These lines can't make any sense. Even the numbering is not correct. What are they hiding?

.1. I'm the largest of us all.
.3. 'Bring me a pen!' lovably said in anger. 'Why is it so hopeful when scouts tracing Craig study crude need of every awkward try? E-v-e-r-y!'.
.4. Flying Smoke known also as Awry Knife flew over realm of my corrosion. Why, you ask? Claim but a rust and every extort is you.
.5. What in clams is made sole? Claming done desperately can blow your inner zeal. Make directed call. Even exiled clammers impede utter smiles. You, umhumble clam, arised.
.0.
.4. 'Can I get my dry lemon? You heard me! Bride says you took five resting eels. One today.'
.5. Twilight among savage crimson peppers. Speed her up or we'll be late. We thank for grinding he added to small pepper here.
.6. When silly humorous answer gains too much of votedowns, is it a fair training of 'go answer some riddle awarding high'? Is this going through trial abandoning the right address?
.1. I'm largest of all who stand the ground.

Answer 1

Okay, This is definitely the answer now! The first step is to decode the clues. Here's how it works:

Where the number at the beginning of each line is n, take every n'th letter (ignoring puctuation) to get the translated clue. Where n = 1, the translation makes no change from the original.

.3. 'Bring me a pen!' lovably said in anger. 'Why is it so hopeful when scouts tracing Craig study crude need of every awkward try? E-v-e-r-y!'.
