I was a little late to the dialogues party a few pages back, here's my humble contribution.
This assumes that Triss arrives with Geralt to KM when they bring UMA:
V: Hello Geralt, Triss.
G: Hey.
T: Hello, old man, missed me?
V: Mmh. Happy to see you. Others, maybe not so much.
(look between G&T)
V: Yeah, she is here, and she threw your old bed down the balcony. (looking at UMA) Who is that, you two have a kid already?
G:I'll explain later, we need to discuss him with Yen.
T:Yeah, where is she?
V: She's set up in your old room. (Looks at the two of the more closely). If my instincts don't fail me, she won't be exactly thrilled to see that you two... Ahh not my business... Just do me a favor and have your little reunion outside, the fortress is battered enough as it is.
G: What?
T: (lauhging)Don't worry I'll behave.
(G&T enter the fortress. They look at the wreckage)
G: It was a good bed.
T: True, not that we ever needed one.
(They enter the fortress and enter the room)
Yen is coughing and cursing as the megascope explodes.
T: Hey Yenna, I see that you made yourself comfortable in MY room.
Y: I'm not in the mood for this shit right now.
T: Bed was causing problems with your communications, that why your threw it out?
G: Triss...
Y: Listen little girl, that bed-
T: Was MINE... actually it was OURS-
G: Triss, the fortress.
T: (draws breath) Fine... Yen, how are you?
Y: (takes a moment to compose herself). "Very good" and you?
T: Managing... Do you know where you are?
G: Triss, enough.
T: Not what I meant. Yen, you do realize you are in KM right?
Y: (Glare)
T: If you had ever been here, you would know Witchers live here-
Y: Your point? Or would you rather end up like this megascope here.
T: My point, Yen, is that witchers use BOMBS, some of them with demirium. If I recall, Lambert was quite fond of-
Y: (Yen understands and interrupts her) I see, in that case, won't you be a good little girl and find them? Here (hands the weird device).
T: Sure why not? Geralt, help me out? I can tell she needs to cool off for a bit.
(both leave)
G: Triss, what the fuck was that?
T: Sorry Geralt, got carried away, reminded me too much of old times.
G: Just be civil, we are all here to find Ciri.
T: I know I know and I'm helping. She didn't have to take over my old room though.
G: She's... Whatever, let's find the dammed things.
