This chapter is manga original as far as I know, there might have been a store bonus side story that we never got in English but I'm happy we still got Raphtalia's perspective during this arc.
Glass's feelings were captured perfectly as she first appeared as an enemy in the story and now is a "temporary ally" with the people she tried to kill, her cold attitude towards Raphtalia shows her conflicted feelings about this entire situation until she met Kizuna again after a long time where her face lit up in happiness.
While looking at L'arc and Therese, they have a friendly attitude towards Raphtalia as they first met as friends and later became enemies.
I've said this a couple of times already but this is IMO the best arc in the entire story and I don't really understand why people hate it and call the author clueless or say that the author is forcing things together. I honestly think these people just skim through the pages and say that they've "read" it
