The dialogue before the fight is great
Shield Knight: When the amulet shattered, the magic within it was released! It's already gathering. It will escape and wreak havoc on everything...
Shovel Knight: Unless we stop it.
Shield Knight: Unless we stop it! We can destroy it for good, here and now!
Shovel Knight: But we're both weak from battle!
Shield Knight: I've never been more ready. Come on, Shovel Knight, let's fight together, like old times. Now... stay close to me!
