thanks all !
yep there's a second spike on this one.
I've had this plant for 4 years and it's its second bloom (did not bloom last year). This plant has been doing much better since I started growing it "sh style" (= with a reservoir underneath the pot) but in traditionnal mix, not clay pebbles. of course it means the media breaks down faster and I have to repot every year but all my besseaes seem to like it (I live in southern France where it gets pretty hot and I found out this is a good way to keep the roots cooler)
