In Large Washington Tablet (S) we have a similar sequence too, though shorter:
I guess that Sa2-116 belongs because of the sitting posture and the sign of darkness.
Sa2-116 Sa2-117 Sa2-118 Sa2-119
Rei and niu seem to be a separate clause in some way.
Hb12-26 Hb12-27 Hb12-28 Hb12-29 Hb12-30 Hb12-31 Hb12-32
Eb6-4 Eb6-5 Eb6-6 Eb6-7 Eb6-8
I believe that the 2-glyph sequence at left also is a separate clause. It is present elsewhere among the texts of rongorongo, sometimes with henua at left sometimes at right.
Sa2-120 Sa2-121
Hb12-33 Hb12-34
Eb6-9 Eb6-10

In Small Washington (R) there is also a similar text.
