Mercury goes Retrograde in Scorpio, and stays that way throughout the month of October. For everyone this can be a time-loop, with things coming back out of their past. That's not always a bad thing, though...
Aries could use extra sleep this month, and should watch for ex-partners coming back into their life. Taurus can also expect ex-partners and old friends to come back into their life. Leo is busy this month, and will be particularly creative with their words, but should be cautious with their transportation. Librans will have things looping from their past, giving them a second chance to wrap things up. Scorpios should use this Mercury Retrograde as a chance for reflection. Sagittarians will meet and hang out with creative people, who can help tweak their future goals.
