Well the sub came out for the episode when Ash loses to Bianca's dad. The scene where Ash snapped at Iris, was just because she was stating the obvious. She was clearly concerned and said "You lost, does this mean that you're going back to Masara town?" Still don't know why Dento was so shocked, Iris was clearly worried.
I find it interesting that she wanted Ash to convince her father. Why didn't she do it herself, or ask Dento himself to do it? I guess Ash is supposed to be the most convincing person out of the trio.
That's what I thought happened with that whole scene. Iris loves to give these deadpan statements so it's really not surprising at all. I know she was concerned for Ash but that was kinda funny It's kinda like the elephant in the room where everyone knew what Ash's loss meant but she's the only one that came out and said it
I noticed that too and thought that was very interesting how she wanted Ash to speak for her XD I mean it's not like she can't be convincing either, probably more so than Ash Yeah Dento could have done some convincing by using his sommelier skills but she wanted Ash to speak up. It's kinda weird but still nice to see ^^
