Birth by Sleep Eraqus' fate? **Spoilers**

So far I've seen vids of what ultimately happens to Master Xehanort, Terra, Vanitas, Ven, and Aqua.
I haven't seen anything about Eraqus.
Someone told me that Terra fights and weakens him and MX kills him.
In the ending, it shows Aqua's armor and Keyblade. Then it shows Aqua being attacked. I was wondering if Aqua could still summon her Keyblade and thought it was weird that

Spoiler

she's still alive during KH2,

but her Keyblade is materialized somewhere else. I expected her to summon her Keyblade, or to be screwed. However, she summons Eraqus' Keyblade.

Fast forward to 3:30.
How does she get it?

Well the reason she is still alive in KH2 is because she apparently got stuck in the realm of darkness for 11 or 12 years I think. Also time moves slower in the realm of darkness so that is the reason she hasn't aged a bit.

 

Hmmm, how exactly does Eraqus get blindsided by MX? It just looks like he collapses after fighting Terra.

 

It says in the subbed secret ending that Terra is looking after Master Eraqus' heart like what Sora did with Kairi's.

 

Aqua gets Master Square Enix's Keyblade before she created Castle Oblivion.
