Robin still couldn't believe that Marth was a girl. And to top it off, he shared a room with her! Even though it was only one night, it was the most embarrassing thing to ever happen to him. She even used his chest as a pillow! Robin's face went scarlet at the thought of it.
"Hey Robin, what are you thinking about?" asked Chrom with a mischievous smile. "Huh?" Robin said as he snapped back into reality. "I can tell by your face turning different shades of red that something happened." Chrom explained. "I don't want to talk about it." Robin replied, eager to change the subject. "Anyway where are we going to next?" "Ferox. Now, tell me what happened."
"Bye Chrom!" Robin hurriedly said as he decided the meeting wasn't worth it. He sprinted outside from meeting tent. "That sly dog." Chrom said to himself as he thought about what to do next. "Maybe I'll talk to Sumia and get some free pies." he thought as he walked towards her tent.

"Hey Marth, you in there?" Robin asked as he walked towards their shared tent. "Yes." Lucina said in her deep, unnatural Marth voice. "I have tell you something." "What is it?" "You can drop the fake voice. I know you're a girl."

Lucina visibly flinched. Keeping her cool, she asked, "How did you make that assumption?" Lucina said calmly in her fake voice. "Well first of all, you look like one, and your body figure sort of gives that away. Also, you were using my chest as a pillow." Robin said all of this with a huge blush, especially at the last sentence. Lucina also developed a similarly intense blush at the last sentence. "I am so sorry!" She suddenly said in her usual voice. "It's alright." Robin said. Robin had never heard Marth's usual voice, but from the drastic change from her old voice to her new one, Robin had no doubt in his mind that this was Marth's real voice, and that she was a girl. Then he asked Lucina, "But why are you hiding your gender? Even when you introduced yourself at the Shepherds barracks, you said you were a guy. I'm sure no one would mind you being a woman. We have plenty of females here in the Shepherds"

"Hmm… I guess it's no use trying to hide it from you." Lucina mused, giving up. "I'm trying keep my identity a secret because if the others found out who I was, there would be… complications." Lucina responded slowly, making sure that she wouldn't accidentally say the wrong thing. If anyone found out that her name was the same name as the yet to be born princess Lucina of this time, questions and rumors could start flying around.

"Well," Robin replied, "you don't have to keep that mask on when you're just with me. Besides, I'm sure you're beautiful underneath it."

The moment Robin heard himself say those words, all the embarrassment of the situation rushed back. "Wait, wait, I didn't mean it like that!" Robin quickly said, trying to somehow take back what he said. But the damage was done and they were now in an even more awkward position than before.

"Well, you don't have to take off your mask." Robin finally said, trying to break the awkward mood. "It's completely your choice, you don't have to if-"

"No, it's ok." Lucina said, interrupting Robin. "It's fine. I'll only take it off when we're alone."

Lucina then took off her mask. Robin gasped and remarked, "Why would hide your face? It looks astounding!" As soon as she heard him say that, Lucina blushed. "Especially your eyes." Lucina then looked away.

"For good reason." Lucina thought to herself.

"Well, I'm pretty sure Marth isn't your real name is it?" Robin asked.

Lucina decided to confide in Robin one of her most kept secrets, her name. If she openly stated it, and Lucina of this time was born, there would be questions why the royal princess was named after one of the Shepherds. Lots of bad things would happen. However, if there was one Shepherd she could trust, it would Robin. Not only was he her father's Chief Tactician and Royal Advisor in her time, he was also her most trust worthy friend. He was also dashingly handsome (not that she would ever tell him that any time soon.)

"My real name is Lucina, but please do not tell anyone. Even the Shepherds. Especially Chrom. If anyone were to even know my name, things could go very, very wrong."

"I would never! I won't tell a soul, not in a million years. Do not worry, my lips are sealed."
After he said that, Lucina sighed in relief, as now she could let her secret safely with Robin. Lucina would admit, it was starting to get troublesome keeping the Marth persona around Robin and everyone else.

Knowing that Lucina would now trust him, Robin remarked, "I feel like we've known each other for years with all the trust we share. Don't you?"

Lucina smiled. That was the fist time Robin had ever seen Lucina genuinely smile with her time with the Shepherds. Robin kept thinking about how cute it was until Lucina replied "Yeah, I do feel that way."
