Ok, i stan this Geordo being jealous and here's is why : This Geordo pressuminly always had what he wants, ( not like in the main timeline where Geordo since kid had to deal with the frustration of not getting all of Katarina's attention and almost never get a time alone with her) but since THIS Geordo doesn't care of anything before meeting Katarina as Bakarina (like in the main timeline where as a kid he didn't care of anything until she spiced is life) This Geordo is discovering bakarina, he's intrigued by this drastical change of attitude and he is starting to care but without being 100%clear with hi own feelings but he is starting to care about her like in the sword fight chap, and he might be jealous unconsciously because and as a prince always had what he desires is more complicated for him accept the fact than Katarina won't always give him attention, so that's why he is jealous even without his feelings clear, and also If game Katarina before isekaided was always after him and suddenly Bakarina doesn't give him attention is a mix of the "realize what you had when you already lost it"effect and also she is his fiancee (legally) and is hanging out with a teacher whom seems kinda sus... So I stand alt Geordo being confused and jealous but even without his feelings clear (oh my... This comment is a mess, thanks for reading)
