Cause I believe Kimberly is scared of making Trini hate her as well
Kimberly: (giggling) Oh what you mean like that time you tore open your shirt in gym cause you shoved too many Dodge balls up there.
Zack (in the background): Wait what. Please Kim, tell me this story.
Trini: (now annoyed) thanks Kim, now he's never gonna let this go, I asked you not to tell anyone. Christ, you can be really annoying sometimes, you know that?
Kimberly: (face falling) oh-oh right. I-I'm sorry. I didn't realise how- I'll just go.
Kimberly stands up, grabbing her things. Trini notices her bottom lip trembling, Kimberly obviously trying to mask her pain.
Trini (suddenly feeling very guilty): shit Kim. I didn't mean it like that. Don't go.
Kimberly: no. No it's fine, I'll leave. I'm the one who should be sorry. I promised I wouldn't tell anyone and I broke that trust.
Trini (grabbing Kimberly's wrist, speaking softly) Kim. I'm not Amanda, I don't hate you. I was just annoyed, and you didn't betray me. You don't have to go.
Kimberly: you don't have to say that cause you feel guilty.
Trini (pulling Kimberly down next to her, Zack noticing this and leaving, giving the duo some privacy): I'm not. I say things I don't mean when I get annoyed or angry. I wasn't angry at you, I was annoyed cause I knew Zack would use it against me in some way. I didn't mean to make you think I hated you.
Kimberly (struggling to keep the tears from falling): it's just... After what I did to Amanda. I'm so scared everyone's going to hate me and leave when you all realise how much of a bitch I am. I'm scared you're going to leave me and I-I... I can't lose you too.
Trini (quickly pulling Kimberly into a tight hug, the Pink Ranger's body shaking as she sobbed into the Yellow Ranger's shirt): we're never leaving you Kim. I'm never leaving you. You're stuck with me.
Kimberly: you say that like it's a bad thing.
Trini: to most people it is.
Kimberly (she murmured, leaning slowly up to the Yellow Ranger): I'm not most people.
Trini (her voice breathy): Kim. W-what- what are you doing?
Kimberly: something I've wanted to do since we jumped off the cliff.
Trini: you mean when you dragged me down with you.
Kimberly (giggling slightly): eh. Tomato tomato.
Before Trini could retort with a sarcastic comment, Kimberly softly pressed her lips to Trini's. The shorter girl tasting the soft tears on Kimberly's lips.
Trini (after pulling away, causing Kimberly to whine): I take back what I said earlier. You are definitely not annoying.
Kimberly: if that's what you think after I kissed you, maybe I should do it a bit more.
Trini: maybe you should.
Before they could though, they heard Zack cheering in the background.
Trini (seething): I swear, if he watched all of that, I'll use him as my personal piñata.
Kimberly: have fun.
She watched as the shorter Ranger chased Zack, hearing his screams as he ran out of the room, Kimberly wiped away her tears, all previous fears leaving as she gently touched her lips.
Kimberly (whispering to herself): yeah I'm definitely fucking bi. Without a doubt.
