Drako:  
sparring with Fluttershy  
Very good Fluttershy that was near perfect  
Flushy:  
But I barely tapped it  
Oh  
I’ll never be a good protective mom  
Drako:  
Nonsense~  
First you perfect your form  
Then you focus on improving your strength  
If you tried strength first you’d never perfect the form you need  
You underestimate your skill  
I bet that even if you fought Dash you’d win easily  
Dash comes in  
Dash:  
How appropriate  
Cause I’m gonna beat up that little runt Scootaloo you’re protecting  
Dravo:  
pulls Fluttershy in front so she shields him  
Dash:  
Not this time  
Outta the way Fluuter-  
pushes her aside  
Fluttershy:  
counters and slams her into the ground  
Dash:  
How did you?  
Nevermind  
I’m gonna get you first  
sends a flurry of attacks  
Fluttershy:  
throws Dash to the ground with each strike  
Dash:  
okay  
you win  
Fluttershy:  
YES YES YES  
I did it!  
I beat Rainbow Dash!  
Dash:  
how did you get so strong Fluttershy?  
Drako:  
you assume she’s strong?  
Dash:  
well duh  
how else could she beat me?  
Draako:  
Flushy just used the momentum of your moves to counter you  
She used your own strength against you  
She doesn’t need any strength at all to beat somepony  
She just needs a stupid pony who uses strength without skill to fight her and she’ll win everytime  
Trust me Dashie, your technique is useless against hers  
And Now I leave Scootaloo in your capable hooves Fluttershy  
leaves  
Fluttershy:  
Don’t feel bad Dashie  
I don’t want us not to be friends  
Dash:  
tears well up  
Why Flushy?  
I used to be so awesome  
Now you’re the cool one  
Flushy:  
really?  
Dash:  
you can fight better than me  
you can fly better than me  
Why did he choose you?  
Fluttershy:  
I’ve been practicing all day and night for that few months  
It’s a lot of hard work  
Dash:  
why would you bother Fluttershy?  
what’s the point?  
Flushy:  
I can’t let you hurt Scootaloo  
She’s my daughter and I must protect her  
Dash:  
so it’s your duty?  
Flushy:  
No~!  
I love Scootaloo  
I’d do anything in the world to keep her safe  
I never want her to feel sad and unloved ever again  
Dash:  
why?  
because you’d feel bad?  
Flushy:  
NO~!  
It has nothing to do with me  
She would be so upset  
And I care how she feels Dash  
I care how she feels  
It’s not for at all  
Dash:  
I don’t get it  
Why would anypony care what other ponies feel?  
Fluttershy:  
When you are a mom  
You will understand

He may be a pet but Fluttershy does refer to herself as his mother. Isn’t that how most (loving) pet owners feel about their pets, though?

But he’s a pet, not a son. A pet who acts like an abusive boyfriend.

Angel is Fluttershy’s son?

>From your son, Angel
 
Did you just make me feel a feel on Christmas eve?

It only he actually acted like this.

:3

D’awwwwww… let’s have some more.
 

Don’t know if this will stop Derpibooru from hating him, but it convinced me.

…  
this strikes a chord in my heart.  
And it makes it feel warm.

Angel did indeed get much better as season 2 went on.
