On the eve of the State of the Union address, Bartlet collapses in the Oval. Abbey rushes home. Leo figures out that there's something they're not telling him...and the multiple sclerosis plot line, one of the most compelling in show history, is off to the races. Some strange magic is in the air, as Mallory kisses Sam in appreciation for his President's letter of support for Leo, then C.J. gets Danny into her office and kisses the hell out of him.

As if that's not enough, we've also got a little Fitz and some Lord John M.
