After Ali Rose was cured at the hospital, she and Alex went to Lake Foleanna to meet Alex's father, Sol.
Alex: Father, I'm hither.
Sol: (Appears in front of Alex) Hello, my son. Great to see you.
Ali Rose was wandering around the lake and found some kind of glove and picked it up and put it on. But she couldn't take it off.
Alex: Father, have thou got the same condition Ali Rose had?
Sol: Yes. But this one was a lot weaker because I have a much stronger heart. Your aunt Moni and Kelly cured me and Fephiles never infected me again.
Alex: But what about me and Ali Rose?
Sol: Your mother was born to a family with weak hearts. You have that gene from Luna. And Ali Rose...her father told me before he died, Ali Rose's heart was injured during the accident that killed him. This caused her heart to be weak. So if she faces what is attacking her, her heart is unstoppable. But when facing the other way, her heart gets attacked easily. Which explains why Fephiles attack Ali Rose and infected her so easily.
Alex: (Puts his hand on his chin) Yeah that does explain a lot.
Sol: (Sees a mark on his son's arm) Alex, I see the mark on your arm.
Alex: What? (Sees the mark)
Sol: Alex my son, if Luna's sister doesn't remove that mark, a virus will attack your heart. (Disappears)
Alex: (Looks worried but hides it as he returns to Ali Rose's side) You wanna go for a walk?
Ali Rose: Sure. I have something to tell you anyway.
Alex: Me, too. (Was about to tell Ali Rose his feelings for her, but he starts to cough up blood)
Ali Rose: Alex! What's wrong?
Alex: Please...take me...to my...castle. (Passes out)
So Ali Rose went to Castle Fire to tell the others what happened. After she got to the castle, everyone looked worried.
Valerie: What happened?
Ali Rose: We were walking until Alex was coughing up blood.
Moni: Oh no. It's getting worse than I thought. Mayella honey, you help the others watch over Alex while I get the cure.
Mayella: Right, mother.
Alex: (Wakes up and takes Ali Rose's hand) Ali Rose, even if I die, I'll always be with thou. (Goes back to sleep)
Ali Rose: (Walks away angrily)
Victoria: (Follows her cousin) Ali Rose, what's wrong, lil' cuz?
Ali Rose: I caused all this trouble! I'm the one who gave Alex my illness!
Victoria: Ali Rose, calm down. You didn't cause anything. Moni said so.
Ali Rose: (Punches the wall)
Alisha: (Puts her ear on Alex's chest) Alex's heart stopped!
Ali Rose: What? Get the electric irons quickly, Alisha!
Alisha: Right. One, two, three. Clear! (Gives static but Alex's heart is still not going) Moni, please hurry!
Moni: Okay! Okay! (Uses the cure on Alex)
Alex: (Wakes up)
Ali Rose: Art thou okay, Alex?
Alex: Yes I'm feeling much better.
Alex was feeling better thanks to Moni and Ali Rose and Alex went back to the lake to see Luna.
