Do Yu's friends not notice that he can use multiple persona's

I just finished the true ending of golden and since I'm doing a run of all persona games for the first time and the last I played was 3 I couldn't help but notice that in high contrast to persona 3 in 4 Yu's friends don't talk about how strange it is that he can use multiple persona's, of course we know it's cause he has the wild card, but since a big point in the game is finding out what persona's and shadow actually are and that they point out that Yu's didn't face his shadow would make the question important to try to find the truth

I could've have missed some dialogue maybe or just my memory is foggy (pun intended)
