Ok, more observation, more surprise, some new finding, some presumption, one problem, and another new grow!
Since the dark skin around the bulb has dried up and broken apart, I peeled most of it off and the light-color fresh skin showed up. From pic1&2, one side of the bulb has an apparent bulge-out bum which I thought was some mutate (deform) when it arrived with dark skin covering the bum. Now I assume it's a baby pop still hold on to the parent bulb. I can see the 1st and 3rd new leaves grew starting from the pop and followed parent's neck curve (under parent's skin) to the top then shoot out. If it is a baby, sure it loves to grow! So the mother has grown a leaf and (hopefully) a scape from center. Now from pic3, see a problem come for the scape: the light comes from slight angled skylight; if I turn baby's leaves to the light, they will block the scape; if turn mother's leaf to the light, it will block the scape and baby's leaves will fall over to press and cover the scape. Alternately, I can turn the side of the scape to light, but all leaves (baby's and mother's) will turn to center to cover the scape! I really couldn't find a good angle to turn for the sake of the scape. Any suggestion?
And then, it comes another new grow from the mother at center on one side of the 2nd leaf (another side is where the scape out). From pic3, the new grow is blocked by the crazy 're-grower'. I have to bend the re-grower down to see the new tip behind. It mostly looks like a leaf though. I'll see if it can out-grow the 're-grower' later.
