I’d say Spike and Rarity remains pretty platonic friendship or no hints at all.

This is the first time Spike actually fights against Queen Chrysalis in canon. Because the Guardian of Harmony toys have Spike to fight against Chrysalis before this episode long ago.

That seriously was a Sparity moment. Unfortunately, they were in the middle of the fight and couldn’t talk much.

I always knew he had it in him.  
The iceberg, the metal lock in just 2 seconds, the storm king’s minions, the Roc, etc.  
Little guy had more power than people gave him credit for. All it takes is the right incentive.

@IceKitsune  
Yeah, don’t listen to that wperson, they didn’t even watch the show.

@Background Pony #4E24  
I still don’t understand why people don’t get what was happening with the Celestia and Chrysalis fight all these years later. Celestia didn’t expect her to be that strong so she held back some and got surprised when she started to lose. It just happened so fast she had no time to adjust. Even Chrysalis was shocked she won that one.
 
Also this isn’t stupid anyway even if you wanted to argue that Celestia was weaker than Chrysalis powered up on love. In this form she is sharing power between 2 other creatures so there is no way to know if she is as strong as she was before. Even if she was Spike had molted by this point clearly increasing his strength and Rarity we had almost never seen fight up till this point so we didn’t know how strong she was. Plus both of them only lasted a few seconds at best against her anyway until they combined their efforts.

@Background Pony #4E24  
I would try to make a point that Chrysalis was powered up at that time too, from feeding off Shining Armor’s love, but seeing as she’s even more powerful now, than she was then, I’d have to agree.

People, don’t forget what Spike does in the movie with the storm guard.  

@Background Pony #4E24  
Spike’s firebreath melts iron in seconds. Chryssie’s lucky to be alive.

This was just plain stupid, considering Chrysalis beam outdid Celestia.

@Background Pony #7348  
Haha!

Watching all those Godzilla movies paid off for Spike!

@genervt  

What is a bug to a dragon?

Go Spike show her WHAT a Dragon are made of!

His love is more powerful then you Chysalis.

@Background Pony #4ECF  
Eeyup.

See no one believed me when I said Spike could take on Chrysalis

Of course, it makes sense for Spike to defend Rarity from the ‘love-eating parasite’.

Spike is badass!!

That’s Spike the badass.

@Background Pony #47F0  
Sorta, yes, it was nice, maybe i was expecting a lot more, like they giving words of encouragement to eachother.

@Background Pony #8112
 
Spike saving Rarity and vise-versa isn’t “Sparity” enough for you? :/

@Background Pony #47F0  
no, i mean, AFTER that episode, no gabby? not even a sparity hint? its like they say: well boys, all done!
