The part with the wing... ugh, I hate that stuff, please keep that to a minimal...

granted she doesn’t bleed out by then.

The slight loss of blood making her delirious, Fluttershy weakly managed to whisper, “I love... I-I will always l-love you...m-m-mom...” She uttered the words before losing her voice.

Ok... So Fluttershy is passing out due to loss of blood, huh? That means that if she isn't immediately tended to, she has a fairly high chance of actually dying.

“I love you, my little filly.” Twilight said before kissing her yellow filly on the forehead as she was passing out.

Twilight would never respond like this, unless she was a dark, twisted freak who liked to see her friends bleed out while in diapers. The first thing she would do would be rush to her side in alarm and shock, assessing the situation. She wouldn't say I love you, my little filly. How would you feel if you were bleeding out, and someone walks up to you and says I love you? You wouldn't give two shits; you'd yell at them to save you.

This chapter needs some major revisions.
