Remember his Friends and Going to Teenage Robot World

They are back in Castle Oblivion and then Susan appeared

Daffy: I bet you're working with Ken.

Susan: That's right. I'm Susan, so... are you enjoying your stay at the castle? I bet it's nice to pull away all the worthless memories and Awaken the true memories... that lie deep in your heart.

Ace: True Memories?

Susan: Although... it seems that you're still forgetting the most important thing here. When that poor bunny hears that you've forgotten her name, why... it's just.. it'll break her heart.

Ace: Poor bunny? Do you know her!? Is she... here?

Susan: Yes. She. Is. You see, the bad guys are holding her captive somewhere deep inside the castle. And you obviously are the hero, so you have to go save her. Although...

She attacked him and then a Good Luck Charm has fallen off of his Pocket

Susan: I'M the Bad guy, so you have to go through me!

Wile: Ace! Are you okay?!

Ace: What's that? Is that thing mine?

Susan: What a shame... You've been wearing it all this time and forgot? No... that's not possible. The memory has to be engraved somewhere deep inside your heart. Ace, you think carefully, now. What oh what could it be? And who gave it to you?

Ace: Ma... Ma..ri...

Susan: Ace... Ace... You've getting it now! Release the memory from within your heart!

Ace: Mari... Marina.

Susan: Well, it's about time. That's right... Marina. Yep, she's the one that gave you that little tacky little good luck charm.

She grab it

Susan: Not that you even bothering to remember. No surprise, seeing as you also couldn't remember her NAME. Talk about Heartbroken! I can't believe you! It'd serve you right if I decided to smash this piece of junk!

Ace: Leave it alone!

He grab it

Ace: Marina gave me this. It's very important to me!

Susan: Oh it's important to you. Ten second ago, you don't know what it was!

He is fighting her and he defeated her
