So, how do we interpret Admiral Picard on the bridge of the Enterprise-E in 2382?
My understanding is that Picard was on the romulan mission for 4 years, from 2383 to 2387.
2379 - Nemesis. Riker/Troi go to Titan.
2381 - Troi gives birth to Thad, new starfleet uniforms
2382 - Titan and Enterprise are near to each other, Picard meets Thad, photo taken.
2383 - Picard leaves Enterprise, becomes Admiral
c. 2385 - Kestra is born
2387 - Picard resigns from starfleet, goes to see some old friends including Riker/Troi, and meet Thad (and todler Kestra). Synth research banned.
2390ish - Thad diagnosed Riker and Troi retire and move to Nepenthe, That being about 10 years old having served on several starships.
2395ish - Thad dies, new starfleet uniforms
2399 - events of Picard
