doctor: thank you for coming princess

twilight: with pleasure ^^ you gave me an appointment for what reason?

doctor: well I have an idea for your biology lessons at your school
heart classes

twilight: ho what a wonderful idea! the heart is very interesting yes

doctor: I plan to examine the hearts of the 6 army members or 6 manes as most ponies say
I take note ... and you will pass them after the results

twilight: I'm impatient!

doctor: can you raise your chest so i can see your heart

twilight: *press the hoof on her chest* oh ... mine too ...

doctor: yes, I'm sorry if you mind

twilight: okay .. i wonder what my heart is like right now ... and .... i feel it banging so hard since i grew up ..

doctor: *vision* wow well your heart and almost as big as princess celestia ...
he beats hard but very calm

twilight: *blush* my assistant number 1 tells me the same thing ... he is a cardiophile

doctor: what is it like to have the heart of an unicorn?

twilight: I feel all of power and magic in my chest unlike before ... I feel every emotion
I especially feel joy in my heart
but the strange thing is that once
I felt like my heart was breaking

doctor: *take note* break it ... as if we broke your heart

twilight: yes, it was painful but now everything is fine

doctor: thanks again for all this princess twilight

twilight: it was nice to open my heart ^^

doctor: can you tell miss applejack to come for an interview

twilight: sure bye
