Clearly the beginning of the new glyph line at Aa2-1 is the beginning of this sequence of events. There are 90 glyphs in line a1 and the last of them ends in a 'spooky' state:

Aa1-90	Aa2-1	Aa2-2	Aa2-3	Aa2-4	Aa2-5
kua oho.	Ko te ohoga	i vai ohata	eko te nuku erua - no te tagata		vero tahi
Aa2-6	Aa2-7	Aa2-8	Aa2-9	Aa2-10
ma te hupee	ka pu te ipu	ka pu - i te mahigo	ka pu i te tamaiti	e tai

At the 10th glyph (henua ora) it is all over. It ends in the 'sea' (tai). The ordinal number is 100.

The hipu sign at left in Aa2-7 contains a little sun child (tamaiti) not yet born, a separate entity from the tagata at right in the glyph. According to Metoro Aa2-7--9 is a triplet group ('ka pu'). In Aa2-9 the child (tamaiti) has been born. I have earlier classified the glyph as pito (navel string). In Aa2-8--9 we see the process of birth and in Aa2-10 comes death, of the mother?

Tagata in Aa2-6 (96 = 4 * 24 = 6 * 16) stands at the final of a cycle and the preceding glyphs tell about a dark sky (Aa2-4) above a great droplet. Aa2-2--3 describe a deep watery haga hole below which there is a world (nuku), the underworld.

In Aa2-1 the gesture of eating has not yet been developed, it is still a closed fist. Aa2-6--7 are standing en face, while in Aa2-8 time has started to move, to go (oho). The bent leg in Aa2-7 is mirrored in the bent leg of hakaturou in Aa2-8. There is a 'mirror' between Aa2-7 and Aa2-8, a break in time. Aa2-7 ends in a ghostly state, exactly as Aa1-90.

Aa2-10 is like a singularity, presumably located at day 50 (= 100 / 2). The newborn sun is blocked from view (cfr Aa2-9). With 2 glyphs per day it is apparent that Aa2-6--7 must be a pair (as day 48 = 96 / 2) - the 'mirror' between Aa2-7 and Aa2-8 effectively cuts time.

Summer (hora) is then announced in Aa2-11:

Aa2-11	Aa2-12	Aa2-13	Aa2-14	Aa2-15
ka hora	ka tetea	ki te rima	ki te manu vaero	ika - ma te kotokotona
