The Colonel's daughter in the picture was quite clearly embarrassed. She's an adult, but taking a wholesome family picture. Like, "Ugh, really dad?" vibes.
Also, I'm wondering if Fiona and Yuri will ever meet up and conspire together. Fiona wants Loid for herself, and Yuri wants Yor for himself. If that were to happen, it would add another level of hilarious shenanigans. Even better, if they ended up subconsciously getting feelings for one another as they conspire to break up Loid and Yor. XD
