To establish a timeline here:
>>2277 that post was made two days after the Rose stream and two days before Bonbi posted about dyeing her hair.
The last OW game was played on the night from the 30th November to 1st December; on the 1st of December Bonbi also posts the Rose pics to IG. After this both Bonbi and Seth go radio silent. Rhonda supposedly stops posting on Facebook around the same time (1st/2nd of December) and her store closes down too.

Certainly seems like something is in the air.
