in japanese version, in timber, before seifer attack the president, the big screen shows a message in english, but that msg make no sense at all, i've heard that it is Adel's interference from space, someone can explain better? (this msg is not in US version)
What happened to G-Garden ater disc 3???
oh, btw, about that griever issue
MY theory:
In present, Squall wished to become as a lion (pride, etc...) and he believed that all that "power" was stored in the ring, so in the future, Ultimecia used all that "power" (or "will") to create the GF griever, so, i think that griever only exists in the future when ultimecia created it... R=U, i don't know, but rinoa had squall's ring, and Ultimecia created Griever GF from the ring's power... well?? ^^
