So the indication of the meaning as a rebound seems kinda true

Working off the apparent general qualities in this question we have a General context of:

issue of values (yin base),
of SHOULD BE (proactive, yang where “could be” is yin)
focus on a REACTIVE process (yin)

= Water; a focus on issues of containment/control, protection, issues of rejection/rejecting. General psyche bias is to issues of security seeking (it covers water and wind). Security issues reflect issues of a lack of trust in others etc that require time to resolve. Water aspect is on protection, a boundary, ‘us vs them’ etc and so to keep something in/out.

Hexagram octet of possible descriptors:

07, 04, 29, 56, 40, 64, 47, 06

Six at the beginning means: “Enthusiasm that expresses itself brings misfortune.”

The man indicated here enthusiastically boasts his aristocratic connection to the great minister in the fourth. He becomes arrogant and egoistic therefore invites misfortune through improper conduct. As this is the first line of the hexagram, perhaps the indicated situation has already occurred – Libby has been charged and probably a few more would be implicated. Since there is no leeway to back track, the prediction moves upwards to the fourth changing line.
