To the water's edge. For, what expands
Before the house, but the great opaque
Blue breadth of sea without a break?
While, in the house, forever crumbles
Some fragment of the frescoed walls,
From blisters where a scorpion sprawls.
A girl bare-footed brings, and tumbles
Down on the pavement, green-flesh melons,
And says there's news to-day—the king
Was shot at, touched in the liver-wing,
Goes with his Bourbon arm in a sling:
—She hopes they have not caught the felons.
Italy, my Italy!
Queen Mary's saying serves for me—
 (When fortune's malice
 Lost her, Calais)
And this is perhaps the dramatic climax, the nub of the poem. It says all that is needed. The possessive determiner “my” and the exclamation mark give emphasis.  The “my” is a direct contrast to the first stanza, in which Robert detaches himself from England. This further exemplifies Browning’s opinions and preferences regarding Italy.
