Welcome to This Week in TV. In a bid to help you prioritize among all the events, premieres, big episodes and finales, The Hollywood Reporter's eagle-eyed TV team will take a closer look every Monday at what to expect from the week ahead — and provide helpful links and context for each. Here's a handy primer for the events that will likely take over the headlines in the week ahead. 

Suits Celebrates a Major Milestone, Wednesday, 9 p.m.

USA's longest-running current series hits its 100th episode. The drama is in the midst of a season seven reinvention following Mike's (Patrick J. Adams) season six prison stint, Jessica's (Gina Torres) move to Chicago and the arrival of Harvey's (Gabriel Macht) old friend and current rival Alex Williams, played by West Wing grad Dule Hill. The special occasion also comes ahead of the backdoor spinoff pilot in the season seven finale, which coincides with the return of Jessica.

Narcos Reboots for Season 3, Friday, 12:01 a.m.

After the unforgettable death of Pablo Escobar (Wagner Moura) in season two, Netflix's acclaimed drug cartel saga returns with a new focus on Colombia’s Cali Cartel, i.e. "the biggest drug lords you’ve probably never heard of," according to the streaming giant. While Boyd Holbrook won't be back, his onscreen partner Pedro Pascal will be. This season, he's joined by new castmembers Michael Stahl-David, Matt Whelan, Halt and Catch Fire star Kerry Bishe and Miguel Angel Silvestre (Sense8). Look for extensive coverage from THR's Jackie Strause.

Diana, 7 Days Offers a New Look at the People's Princess. Friday, 8 p.m.

The two-hour doc special commissioned by the BBC makes its stateside debut on NBC days after the 20th anniversary of her tragic death. Her sons, Prince William and Prince Harry make a rare on-camera appearance, opening up publicly for one of the first times about the week she died. Other interview subjects include former Prime Minister Tony Blair, Alastair Campbell, Earl Spencer and Lady Sarah McCorquodale, among others.

Twin Peaks Says Goodbye (Again), Sunday, 8 p.m.

Agent Dale Cooper, Shelley, Bobby Briggs and the rest of David Lynch's eclectic cast of characters sign off for a second time with the end of Showtime's revival. As has been the case all season, details about the two-hour season-ender are being kept under tight wraps but it seems safe to assume Lynch and co-creator Mark Frost will offer up a truly original farewell for the second coming of the cult favorite.

Power Wraps Season Four, Sunday, 9 p.m.

After delaying the finale to avoid going up against the season seven finale of Game of Thrones and the 2017 MTV VMAs, Starz's hit drama concludes its momentous fourth season. The season ender comes after several shocking character deaths, which will send Ghost (Omari Hardwick) and Tommy (Joseph Sikora) on a quest for retribution in the finale. No matter what happens in the finale and who else may meet the Grim Reaper, the show is safe with a season five renewal already firmly in the bag.
