The oldest pad is producing two fresh buds + more on the way on the other two pads!
Sadly, they aren't flowers.
I'm seeing ephemeral leaves!
Opuntias are positively notorious (especially the pad-type Platyopuntia subtribe) for showing their ephemeral / vestigal leaves.
Is there a picture with your post?
Unfortunately, the computer I use for posting pics is having internet connection troubles. I've only got this laptop. I might get an image or two posted in a few days.
