so the valley girls are Californian..and they have accent, right? I hardly understand them..

There is an "accent" issue, but it is secondary to the "presentation" and "sentence structure" (or lack of it). In that video above, 2 girls show contrast between "regular" and "valley girl" talk.
The girl in glasses uses structurally correct sentences, stating the "issue" without any extra words in between; the "valley girls" adds a lot of exclamations, sounds, unnecessary words, uses incomplete sentences, etc. I'll just translate 3 examples:
Nerdy Girl: "Hallo" (Хэлло)
Valley Girl: "He-aya guys, ee... like haaay-yaaa". (Hey guys! like hi!) (Эй-.хей.. ребятки! ну вроде, как бы приветик там вам всем...)
Nerdy Girl: "How are you today" (Как Вы поживаете или Как дела).
Valley Girl: "So... like..... how are you today.... eeehh.... i have not heard from you in a while..eee" (Ну.....вроде.... как, это самое, дела там у вас?...эээ... давно необщались...)
Nerdy Girl: "Do you have plans for tonight?" (у тебя есть планы на вечер?)
Valley Girl: "Are you, like doing anything later.....? ... like, you know, later tonight? are you?..... 'cause like i really want to do something... do you wannaaa do something? (ты там, ну как-бы, чем-то вечером занята? .... ну как-бы, понятно да? позже вечером? ты занята?.... да па-та-муш-та ну мне хочется чего-то там поделать..... а ты хочешь чего-то там поделать?)

... so, like, you get it now, right? it it's like wow!....... totally narly...
Maybe something like, 'Are you hurt?' or putting an arm around her could have worked....
You are absolutely right. Tzareva knows how to behave properly in public and how to be supportive.... @ Helsinki Worlds all went well in K-n-K (@ 7:10)

Aside from "compassion" issue, Tzareva's behavior in K-n-K @ SC was not productive. Pogo was not ready to discuss and address the technical problems right there and then. But the "negative impact" of the conversation will remain in her mind.
