Twilight helped Derpy & Octavia escape, then they were making their way off the boat.

Twilight: You two wait here. We need Pinkie since she has the map.
Octavia: Oh perfect. You better get her quickly.
Twilight: Pinkie? Come here.
Pinkie Pie: *hops toward Twilight* Guten Tag Twilight. *laughs*
Twilight: Stop speaking german, and come with me.
Pinkie Pie: Nein, ich bin Deutsch, damit ich sie sprechen kann, wenn ich will.
Twilight: What? *kidnaps Pinkie* Row!
Octavia: Can't you use magic to teleport us?
Twilight: I can, but I'm not teleporting you guys.
Derpy: Aaawww.
Tourist pónei, pônei 4: *drives jetski past boat* How much longer?
Tourist pónei, pônei 2: Keep going! Don't stop towing me.
Tourist pónei, pônei 4: I'm getting low on fuel!

That night on the island

Pinkie Pie: You kidnapped me?
Twilight: Yes I did. Now you work for me.
Pinkie Pie: But I thought we were friends!
Twilight: Who would want to be friends with you? Give us the treasure map.
Pinkie Pie: I don't have it.
Twilight: Well then I'll get it, and kill everyone onboard.
Derpy: Doesn't she remember?
Twilight: No. I'll be right back. *teleports*
Sean: Hi Twilight, have you seen Pinkie Pie anywhere? And where did you come from?
Twilight: *Hits Sean* Where's the treasure map?
Sean: You just hit me. Why should I tell you?
arco iris, arco-íris Dash: Is everything ok here?
Twilight: *Shoots arco iris, arco-íris Dash*
arco iris, arco-íris Dash: Ow. What was that for? *kills Twilight*
Sean: Are you alright?
arco iris, arco-íris Dash: My head nearly got shot off, and your asking me if I'm alright?
Sean: Take it easy, Rarity'll get it fixed.

Back at the island

Pinkie Pie: So when did Twilight say she'd get back?
Octavia: I'm not sure. Why don't you take us to the treasure?
Pinkie Pie: *shakes head no*
Derpy: Do it or you die.
Pinkie Pie: Allright I'll help you.

But does she? seguinte part will be posted tomorrow.
