The development opens with descending octaves — the first half of the fugato theme — under statements of the triplet theme which is its second half, in imitation between piano and cello. This leads to C minor, to an inverted statement of the fugue, to another episode-like section (bar 95, based on a part of the fugal opening first heard in bar 16; if this is not a fugue it is indeed very like) and after a brief section again in fugal imitation to a tense and tension-gaining section in true sonata style (bars 105–114, returning us to E minor, again based on the bar 16 figure) and a return to the main key, the second theme instead of the first, in triplets. After a repeat of the second theme, the opening fugato (what one calls a fugal section that's part of a larger movement rather than itself a fugue) returns, quoted in its entirety but staying in E minor rather than modulating to G, leading to the "Più presto" coda.
