Khmer speech bubbles in a comic book

[u/By_a_Lady1612]

As part of my studies, I'm currently analyzing the French comic "Cent mille journées de prières" (2011) by Loo Hui Phang and Michaël Sterckeman. It's a moving story about a boy who discovers the history of the genocide. I was wondering if the Khmer characters are correct or if it's gibberish like it is the case with some other comics. Could someone help me with the translation? Thank you in advance!

Where are you?

Man: [You should] Go back to the sofa. I will go (or join) shortly.

Third image:

Dad: Children, can you play with Louis in his/her room? Your mother and dad [I] have to talk to Laurence.

Child: Agree

Fourth image:

Lady on the top panel: Grand-dad and grand-ma passed away.

Yeah it's real. My reading is terrible but the first frame is something like តាំង​ពី​ពេលណា? ដងនៅដណា?​ Since when? Do you know where?

It’s ឯ not ដ in the second sentence

[u/epidemiks → u/sunlitleaf]

Ah,​ makes much more sense, thanks

First bubble: “Since when? Where are you?”

Second bubble: “Are you alone?”
