3rd house overlay
Their planet in your 3rd house: the relationship lives in conversation and small daily contact.
What this house covers, and how often it fills
This house pairs with the 9th across the chart — belief, distance and what you consider true — and the two work as one axis. A planet landing here is also, by definition, opposing whatever sits there, so the two readings belong together rather than separately.
It is a cadent house, which precedes an angle and is the group traditionally read as adjustment and transition. Its natural ruler is Mercury, so a partner's mercury arriving here doubles the theme rather than adding a new one.
The 3–9 axis
Everyday talk and thinking sits opposite belief, distance and what you consider true. A planet in one is automatically opposing the other, so an overlay here is always a statement about both — the relationship lives in conversation and small daily contact, measured against they shift the frame you use rather than the contents of it.
