While Admiral Croft was taking this walk with Anne, and expressing his wish of getting Captain Wentworth to Bath, Captain Wentworth was already on his way thither.

Before Mrs Croft had written, he was arrived, and the very next time Anne walked out, she saw him.
Mr Elliot was attending his two cousins and Mrs Clay.

They were in Milsom Street.

It began to rain, not much, but enough to make shelter desirable for women, and quite enough to make it very desirable for Miss Elliot to have the advantage of being conveyed home in Lady Dalrymple's carriage, which was seen waiting at a little distance; she, Anne, and Mrs Clay, therefore, turned into Molland's, while Mr Elliot stepped to Lady Dalrymple, to request her assistance.

He soon joined them again, successful, of course; Lady Dalrymple would be most happy to take them home, and would call for them in a few minutes.
Her ladyship's carriage was a barouche, and did not hold more than four with any comfort.
