Mafia 72. "Little Green Man" Bar

What bothers me is this:

"You'll get your revenge later; I've already booked a room at a hotel in Los Angeles."

As she fell, she croaked on her last breath: "You all still owe me!"

Well, the second one can still be attributed to the character's description, albeit with some difficulty. But today:

"Unbelievable! Now I'll make my former colleagues from the Tobolsk Research Institute pay!"

An obvious clue, with no connection to the plot, and to top it all off, there isn't even a research institute in Tobolsk. And

Arandor, with a shattered skull and a broken shell, was found only in the morning.

Here, too, there is no connection to the setting, not even an indirect one. Are these two clues? So, that's how it is...
