At the battle of Helm's Deep
Aragorn and Gimli sneak out to attack the orcs from behind. While they're busy fighting, Legolas hops on top of a rampart to get a better view
Legolas: (peering around) Aha! There they are! And they thought they could sneak off without me noticing. (Turns to closest group of orcs) Pssssssst, hey, look down there!
The orcs look confused, then spot Aragorn, and race down to surround him. Legolas reaches down and grabs Gimli by the hair, yanking him up to the rampart
Gimli: ARGH
Legolas: Shh, Gimli, it's fine, why don't you go punch some orcs?
Gimli: Ooh!
Aragorn: Hey! Guys! I'm surrounded down here!
Legolas: (holds knife up like microphone) Aaaaand ladies and gentlemen, welcome to the highlight of the season, the face-off between Aragorn son of Arathorn, and the horde of bloodthirsty orcs! It promises to be a fight to remember, so hang on tight!
Aragorn: Hey! Can you guys hear me?!
Legolas: It looks like the first group of orcs is closing in, oh yes I see they're going for their signature move, the simultaneous attack, OH would you look at that ladies and gentlemen! Ooh, that's going to leave a mark! Ouch, now that's what I call a low blow. Hey hey hey, that's just uncalled for! Well folks, it looks like our lone ranger is down for the count, and possibly won't return for next season!
Aragorn: Legolas! Gimli! Anyone, can you hear me?!
Legolas: (pokes his head over the ledge) Hmm, did you say something?
Aragorn: Get me out of here!
Legolas: Oh goodness! If you needed help why didn't you say something sooner?
Aragorn: I DID!
Legolas: (surfs down the stairs on a shield while singing the Indiana Jones theme)
Legolas reaches the bottom of the stairs, kicks an orc out of the way, and walks over to Aragorn, who is now lying on the ground.
Legolas: Man good thing I'm here or you'd be toast, huh? Haha! Oh pull it together you big baby, you have a whole other arm after all!
Gimli: Legolas, I… saved the last orc for you…
Legolas: Not now, you psycho dwarf
Aragorn: Guys… guys.. do you hear that? The sky is… really beeping today...
Gimli: Huh, I think you might have lost some blood, buddy
Legolas: Hmm? Oh, that's just my beeper, they need me over on set #31B! See you guys later! (prances away)
Gimli: Dude, Aragorn, you better get up off the ground, or they'll make us redo this scene
Aragorn: Gimli, since when do you have a twin brother?
Gimli: Aw geez.
Frodo, Sam, Pippin, Merry, and Aragorn are at Weathertop when the Nazgul catch up to them. Aragorn is in the midst of beating them back with sword and torch when suddenly, a strange, white light blooms overhead. A girl falls out of the sky, landing right on top of one of the Nazgul.
Girl: Ouch!
Nazgul: SCREECH!
Girl: Yow! (scrambles off of the Nazgul, stumbling in the dark)
The Nazgul attacks her with its sword, but the girl manages to trip it, causing the Nazgul to fall flat on it's face.
Aragorn is still fighting to keep the rest of them away from the hobbits. He defeats one, but meanwhile another is sneaking up behind him, sword raised. Just as it's about to stab him, the girl kicks it in the stomach, sending it toppling off the edge of the cliff. The rest of the Nazgul flee, defeated. Aragorn turns to the mysterious newcomer.
Aragorn: Thanks for your help! But how did you get here?
Girl: Beats me. Oh hey, that guy managed to cut me, dang. (faints)
Aragorn: Aw man! What a cop out. Now I have TWO invalids to get to Rivendell.
