The yuri-otaku in chapter 17 should pair up and have fun talking about yuri manga if they aren't already are lol.
ch.18
Their first mistake is actually considering the crazy idea of trying to kidnapped their former general (Also assuming their former general is now a weak powerless human...She is not, just not at 100% power yet). Their second mistake was speaking about it in public instead of planning it out beforehand or on text message/writing it down silently...amateur mistake.
Also MC's teammates/bestfriendo/two support wingwoman did great job in helping Hana out on their 'totally not a date(Unofficial date technically)'.
Guess Lemon was just slightly shocked and confused that Junna was so casual about being kidnapped by the random monster of the week in chapter 12(Probably was expecting Junna to be atleast a little worried or nervous...Guess Junna got too used to it and having her waifu/Hana save her easy become a daily weekly routine).
Hana 10000% likes Junna which we all know already and Junna very very decent good chance she might like Hana back romantically (At the very least there us a decent 90% chance...We just need more evidence just to be 99.999% confident in our guess...At the very least Junna gets flustered, shy and stuff when Hana is making unconscious contact/getting too close. At the very least, they are both at very very very close friends/Bestfriendo status relationship level. Though Junna might be a little dense in romance perhaps???)
The comment about Junna taking a sh*t as the translation would work out an an total awesome alternation translation (Not sure if that actually counts or can be considered a localization but if it then it in the small minority of good localization then!)...It basically still hold 90% of the same meaning Junna in the restroom (Just assuming she is taking number 2, very humorous lol but Junna would probably kill the translater if she could travel through dimension somehow). Like how a fan translation had a character ability be named Bullsh*t dector instead of lie detector (Almost the same thing and general meaning but more humorous, only small portion won't understand that bulls*it means fake or false). Localization by localizer is often bad 80% of the time sadly due to those people changing the meaning/words/translation to something totally different and into different slangs (Which can change 20-50% of the original meaning/intent) which the next generation that read it will have to look up if they don't know it the slang.
Anyways looking forward to their 'totally not date' in the next chapter.
Lemon is just relax and casual about Hana and Junna's relationship (Already assume they are going out or assumed that they will be eventually end up dating soon, probably replying with cool story bro/sis! Gratz!) While Sou is more of the teasing type that enjoys the fun/antics (She was the one who suggest making Hana ask for a reward in previous chapter if Hana got good grades).
