"Dating? Geez, brother, did you bring your girl from New York? Who is she?" Scarlett was surprised to learn that her brother had brought a female companion to the island. She had assumed he would come alone, so he offered to stay at their place.

"Someone you know!" He said nonchalantly.

"Who? Who is..." Scarlett abruptly paused as a beautiful woman's face flashed through her mind—Sister Casey!? She thought. 

"Hahaha... I knew it. It must be her. All right, have fun, brother. Send my regards to my sister-in-law..." Scarlett continued. She was grinning, but her grin only left Rex puzzled, unsure of whom she was referring to. Not wanting to linger there, he quickly left the room, setting aside his curiosity.

As soon as Rex disappeared behind the elevator doors, Xander turned to Scarlett, who had been lost in her thoughts, smiling blissfully.

"Babe, does Rex really have a girlfriend?" Xander asked, and his curiosity arose. If Rex had a woman by his side, he would no longer have to worry about Rex stealing his wife. He could finally be at ease knowing that Rex Morrison was no longer single.

Scarlett snapped out of her thought, imagining Rex and Casey as a couple. She truly desired a loving partner for her brother, someone who cared for him sincerely, not just because of his wealth and good looks.

And, she knows Casey is a woman who likes and loves Rex unconditionally, despite Rex's bad boy image.

She smiled at Xander and nodded. "Yes, Brother Rex has found someone who truly loves him. Hubby, let's go... I want to send a message to someone," she said, rushing inside to find her cell phone. She wanted to congratulate Casey and express her joy that Casey finally had the chance to melt her brother's heart.

Xander could only shake his head, a smile adorning his face, as he followed her inside with ease and a happy mind. 

...

After locating her cell phone, Scarlett hurriedly made her way to the bedroom, eager to send a private text using a secure application that connected the core members of The Fox team.

[Three: ] Sister Casey, congratulations... you are finally melting my big bro's heart.

[Three: ] Are you on island B?

[Three: ] We should celebrate this! (fire icon) (smile icon)

[Six: ] What?

[Six: ] Explain! (Confused Icon)

"Waaah... Waaah... How could my sister still hide this from me?" Scarlett muttered. A mischievous smile graced her face as she continued typing.

[Three: ] (LOL Icon) Don't try to hide from me, sista!!!

[Three: ] My brother already told me he brought you to Island B.

[Three: ] Now, explain to me... Since when did you two start dating?

In one of the villas in LA, Casey Adams dropped her cell phone in shock upon reading the unexpected message from Scarlett.

"What did Rex tell Scarlett? I'm dating him?" Casey murmured to herself, her voice trembling with excitement. The news made her smile, but she knew she had to clarify things with Rex before responding to Scarlett's question.

Casey quickly retrieved her cell phone from the floor and dialed Rex's number. 

...

As Rex made his way to his villa, a throbbing headache began to trouble him. Thankfully, he had his driver with him, allowing him to recline comfortably in the backseat. However, Casey's unexpected call only intensified the pain in his head. 

"Casey!? Why are you calling me in the middle of the night?" Rex asked, sounding confused.

Taking a deep breath, Casey mustered her courage before speaking, "R-Rex, you... I mean, I..." Her voice faltered, overcome with nerves. She silently cursed herself for always being shy whenever she talked to Rex.

He waited in silence, hoping she would speak clearly and provide some clarity, but her words came out confusingly. "Could you please speak more clearly? I can't understand what you're saying!" he exclaimed, feeling drained after a long day.

"Th-This..." Casey stammered.

"If you don't want to talk, just end the call!" Rex snapped. "I have to go. Bye!"

"No, Rex, don't hang up!" Casey pleaded, afraid that Rex would abruptly end the call. She needed to ask him about Scarlett's message.

"All right, go ahead and speak," Rex said in a softer tone.

"Uhm... this is about something strange," Casey finally gathered the courage to speak. "I just received a text from Three….ugh…. I mean Scarlett. She said you told her that we're dating and I'm in your villa on B Island." She paused, awaiting Rex's response. However, after several seconds passed, there was no reply from the other end.

"Huh!? Did you hang up on me, Rex? Hello..." Casey uttered while checking her cell phone screen in confusion.

On the other end of the line, Rex's eyes widened in shock as he listened to Casey's words. It took him a few seconds to grasp the reason behind Scarlett's assumption, but eventually, it clicked in his mind. He remembered his careless remark before leaving the Beachfront Hotel, and frustration filled his heart as he scolded Scarlett inwardly.

'Damn it, Scarlett Piers!' Rex scolds her silently. 'How could you assume the woman I brought here was Casey?' He remembered, earlier, he just answered her without thinking.

After venting his anger internally, Rex cleared his throat, wanting to reassure Casey that he hadn't hung up on her.

"Oh, you're still there..." Casey's voice sounded awkward through the phone, intensifying Rex's headache. He braced himself as he heard her next question. "So, Rex, why did you tell her we are dating?" Her voice trembled with nervousness as she waited for his response.

"Maybe you heard wrong..." he quickly replied.

"Well, we were chatting over text, not talking on the phone," Casey responded with a growing fluster. "I can screenshot the chat if you don't believe me..."

Rex felt a lump in his throat. Once again, he scolded Scarlett internally.

"I don't know why she said that. Maybe that silly little girl was teasing you!?" Rex said, but when he heard a sigh of disappointment from the other end, he winced. Cursing himself silently.

Rex cursed himself silently, fully aware of Casey's feelings for him but unwilling to break her heart. That's why he never allowed this girl to express her feelings.
