Lisa and Gabriel meet when Gabriel tries to impersonate Maikel to get into Malhaven to kill Felicia. Like, this is AFTER her and Amias's prison sentence (which I will talk about later) and HALT has allowed Maikel monthly visits with Felicia as a reward for her willingly going with them but Maikel knows that Faust would probably target Felicia so he tells Lisa and Lisa assures him that they have a plan. So when "Maikel" comes to visit Felicia, Lisa just meeting him outside and Faust just smiling at her a little because she's kind of cute.
Lisa: "Detective Montoya, welcome back. She's been expecting you."
"Maikel": *nods* "I'd like to see her as soon as possible please."
Lisa: "Of course!"
And Lisa just noticing he's been acting strange and realizing this might not be Maikel so she clears her throat: "Felicia's a lucky girl, you know...I've always had my eye on you, Maikel."
Oh? This just got interesting.
"Maikel": "Uh...Excuse me?"
Lisa: "I don't know when these feelings developed but they just did...I'm not really the kind of woman who chases after a taken man but...there's something about you I can't resist..." and she gently pushes herself up against him and puts her hand on his chest and she ghosts her lips over his.
Lisa: "Surely...one kiss couldn't hurt?"
and Gabriel just smiles, "It'll be our little secret, mi chula~"
and Lisa just keeping her composure but this confirms that it isn't Maikel because he would NEVER be that sleazy but also, he would say: "That's the question, isn't it?" out of pure habit.
So Lisa just smiling and pulling away: "Oh, dear, we're at our floor! Looks like we'll have to pick up after you visit her~" and Gabriel being confused but he did come here to kill Felicia so he just smiles and quickly kisses Lisa's cheek, "I'll look forward to it."
When Gabriel walks into the hallway and Felicia is in her cell, Lisa just walking back into the elevator and once the doors close, she just hums: "Cheshire Cat is in Wonderland. I repeat: Cheshire Cat is in Wonderland." and Vincent just nods and he's all: "Understood. Seraph and The Triplets are on standby."
And Felicia noticing Gabriel and she's all: "Gabriel...What are you doing here?"
Gabriel: "Well, I'm here to kill you and then possibly hook up with the hot director lady-" and Felicia just standing up and backing away from him but when Gabriel starts to turn into mist, the Triplets jumping out of the shadows and they use their staffs to create a magical containment unit around Faust and Angelo stabs his sword into the ground and uses his holy powers to reinforce the strength of the shield so no matter how much of his own magic he uses, he can't escape.
Lisa: "Brava! Brava! Encore! Encore!" and Felicia giggles and she does a little bow while Gabriel glares at both of them and Lisa is all: "Mr. Faust, I know you never faced against HALT before but did you REALLY think you could just waltz into our prison?"
Gabriel: "It's worked for me before. I'll admit, this is a cute little trap but it won't hold me."
Lisa: "Oh, but I beg to differ~ You see, HALT is different from the Justice League, ARGUS, CADMUS, and Arkham in many, many ways. The main difference is...we're simply too good at what we do." and they escort him to his cell and he's all: "...Before I go, can I know the name of the woman who managed to cleverly charm me?"
Lisa: "It's Lisa Song. Don't worry, you won't forget it anytime soon."
Gabriel: "Hmm...Lisa. I like it. Shame that you weren't being serious about the elevator."
Felicia: "What happened in the elevator?"
Lisa: "Oh, just a little test to see if he was truly Maikel or not."
Felicia: "...Do you "test" Maikel often when he visits?"
Lisa: "Yes but this is my first time seeing if he'd cheat on you."
Felicia: "I'd like to politely and aggressively ask you to QUIT testing him."
Lisa, genuinely teasing: "I'll consider it~"
and Gabriel just laughs hearing how Felicia stamps her feet and looks over his shoulder and catches a glimpse of Lisa's smile and he just feels his heart squeeze at the sight of it but then Angelo just tugs him along.
Angelo: "Move it, convict."
And Gabriel glares but he takes one glance back at Lisa before he allows himself to be taken into whatever cell they have for him.
