Where ever Jupiter sits, 2nd from it is where native bring an element of scarcity. The scarcity is done to ensure proper value. It brings in the notion of quality over quantity.
For example: Jupiter in 1st house, native will speak less but whatever s/he speaks, will hold immense wisdom and value. The reason I said speak less is because 2nd house also denotes speech of a person.
Astronomy is at loggerheads with astrology when it comes to Mercury Retrograde, in which Mercury, the planet associated with communication, appears to move backwards and seemingly causes chaos, tension, missed flights, crashed computers and lost phones!
