Question about passing legislation after midterms

[ColoradoBlue]

Let's say that after the mid-terms, the Dems gain seats in the Senate but lose control of the house.

Let's say that there's legislation that has been passed by the House (codifying Roe, voting rights) that has languished in the Senate.

Let's say that by picking up seats, Dems abolish the filibuster.

Can Dems pass the legislation that has already been passed to them by the House? I would assume that it would need to be passed as is so that it doesn't go back to the House?

Or are the mid-terms a "re-set" button on legislation and we have to start all over?
