Should i ask?

Last weekend I said hi to his parents for the first time and since then, he hasn’t mentioned anything about them if they said anything. I’ve made a couple other posts (hi i’m the person who is dating someone outside my culture) and ik that sometimes different cultures and different languages can be something that’s difficult when meeting the parents. Should i straight up ask if they said anything or just leave it alone? i kinda don’t wanna know.... they saw me at a super unflattering angle (i was at the top of the stairs with him and they were at the bottom). i’m scared but i just wanna know. what should i do?
