Mercury governs thinking and speech — how you process and explain. In Leo, that function takes on warmth, presence and the need to be seen doing it — a Fixed Fire expression ruled by Sun.
Where it strains
Needs recognition badly enough that its absence reads as rejection.
Reading a placement properly
Mercury in Leo describes a function in a style. It says nothing yet about where that plays out — for that you need the house, and the house needs a birth time. A placement read without its house is half a sentence.
