What to Watch Tonight: The Americans, Arrow, and the Series Premiere of How to Live With Your Parents (for the Rest of Your Life)

What to watch on Wednesday, April 3...

8pm, The CW
What’s this? Count Vertigo back to menace Starling City with his diabolical designer drugs? Tommy in trouble when a Verdant visitor parties ‘til she drops... dead? Can the Emerald Archer make sure the miscreants responsible get the point? Tune in to “Unfinished Business” tonight—same Arrow-time, same Arrow-channel!

8pm, PBS
Nature: What Plants Talk About
This hour-long look at the latest research on plant behavior explores whether they communicate just like we do. I'm assuming plants mostly discuss the weather and that new Indian restaurant downtown and whether Elena would be better off with Stefan or Damon, but what do I know?

8:30pm, ABC
As Suburgatory nestles into its new timeslot with “Decemberfold,” George thumbs his nose at the buttoned-down strictures of the “family hour” by participating in a racy “Dads of Chatswin” calendar. Meanwhile, Lisa’s suspicions are aroused when Dalia is unusually friendly to Tessa.

Spies of Warsaw
David Tennant stars as a French military attaché (not called simply, “The Attaché,” sadly) who becomes enmeshed in the diplomatic intrigues of interwar Europe in this two-part special based on Alan Furst’s novel series. Part one finds him taken aback by both an alluring Parisian lawyer and a chance discovery of German military preparations.

9pm, The CW
To tackle the Tablet’s second trial, Sam and Dean enlist the services of a reaper in “Taxi Driver.” Dean also realizes that he needs to track down Benny for a huge favor, so his fingers are crossed that today is the day of Benny’s daughter’s wedding.

How to Live With Your Parents (for the Rest of Your Life)
Straightlaced Polly (Sarah Chalke) must move back in with her flighty mom and stepdad (Elizabeth Perkins and Brad Garrett) after her divorce leaves her overwhelmed by single motherhood. Will her cautiously structured hot front and their freewheeling cold front collide into a thunderstorm of sitcom hilarity?

10pm, NBC
Chicago Fire
Severide endorses Mills’s bid to join Squad, but his colleagues aren’t quite as enthused, probably for fear of disrupting the highly delicate chemistry of their intramural 16-inch softball team. Rounding out “Ambition,” Dawson and Shay are shadowed by a paramedic candidate, Shay lends assistance to a woman facing pregnancy complications, and Casey welcomes a surprise guest.

10pm, FX
The Americans
Philip and Elizabeth are on their heels when a routine mission goes awry in “Safe House,” while the FBI is knocked back by an agent’s disappearance. Claudia, meanwhile, can’t shut up about the quirky Elvis impersonator she met in Chicago last week.

10pm, TNT
A drug dealer’s funeral incites trouble in the streets, and Lydia and Ruben’s investigation into the murder of Sgt. Hill’s son incites a quandary over police corruption. Elsewhere in “The Felix Paradox,” Ben begins to suspect the truth about Sammy and the tape, and everyone tries not to make rapping-genie jokes when an officer who looks suspiciously like Shaquille O’Neal pops up.

10pm, USA
Gus stumbles into danger while babysitting Rachel’s son in “Cirque Du Soul.” Their circus visit includes more dead bodies than one generally prefers to encounter on a circus visit, though perhaps the deceased’s orphan son will become the youthful ward and eventual crime-fighting partner of a billionaire playboy.
