Transcript & Bonus:
A strange woman wearing all black who held onto his keys for a bit too long. What could be going on here?
...
[Bryce stayed calm and composed in this situation. He didn't want to ruin this good night, so he kept the conversation going saying he did know her. But he needed to speak to Renee alone. Leilani could tell this from Bryce's expression and so she asked Vincent for a tour of the restaurant, to give them some alone time]
Renee: Dad you look worried, what's wrong? Don't tell me it's to do with Vince…
Bryce: Please don't get upset with me darling but [heavy sigh] are you sure about Vince?
Renee: Why are you asking me that? From the dinner, you seemed to really like him.
Bryce: I know. I do really like him, but I'm not so sure about his Mum or his family even.
Renee: [gets upset] What does that have anything to do about our relationship?
Bryce: His Mum and I have history. Let's just say she cheated on me, so I don't have a good feeling-
Renee: [stands up] What?! You didn't say any of that just then! I didn't even know you dated anyone else.
Bryce: That's all in the past. You don't need to know any of it. Renee…we can see that Vince makes you happy and your happiness is what matters the most to us. But I want you to be careful with him ok?
Renee: Dad...not everyone is like their parents. I think you're seeing too much of his Mum in him and you're judging him based on that along with your past experience. He's his own person. Like you said, it's all in the past. From the way Vince talks about her, surely things have changed and she's not the same person you knew.
Bryce: [hugs her] Renee, I'm looking out for you, I don't want you to get hurt again.
Renee: He won't hurt me Dad. Vince is a good guy. Even Billy says that and don't you trust him?
Bryce: [reflects back on his own words] You're right. I trust him with my whole heart.
...
[Vincent reaches for his pocket to answer a call and drops his car keys]
?: [picks up keys and holds onto to them for a second too long] Sir, you dropped your keys.
Vincent: Oh thanks. [to himself] Why's she looking at me like that?
