My turn to answer my own topic (or rather cilan's topic):
How do you think ash and iris will confess their feelings?
i was having the same thoughts as you Pikachuuu, except that iris takes a critical pokemon attack for ash. She then falls to the ground and ash, with an angry and wishful voice, asks her why she did that. I guess since it's pokemon, they wont make the characters say it straight forward, so Iris would answer something like "I did it because I...I...I deeply care about you." and then she faints.
Like most of you said, this might either
1. Happen in a movie and then get forgotten or
2. Happen at the end of the series (probably not, if the pokemon series ever ends)
