Agents of SHIELD is quickly moving away from family-friendly fare.

The Marvel series entered the ABC lineup three years ago, debuting in the 8 p.m. timeslot. Since then, the drama has moved to 9 p.m., and, when season 4 hits screens this fall, fans will have to tune in at 10 p.m. ET. Jumping to primetime's latest hour will give Agents of SHIELD a chance to head in an adult-oriented direction, pushing the series closer towards the tone of DC's Gotham and further from the all-ages world of Supergirl and The Flash.

"I think it's great. I think we've got progressively darker each season and it's great to be able to push those boundaries a little bit," Elizabeth Henstridge told Digital Spy at MCM Comic Con in London. "I think the writers are excited, because they'll be able to maybe get a little bit sexy... throw in some good swearing!"

Perhaps Agent of SHIELD will use this opportunity to heat up a few of the series' intraoffice romances. Daisy (Chloe Bennet) certainly isn't looking for love in the wake of Lincoln and Ward's deaths, but FitzSimmons is on the move and no one missed the undeniable chemistry between Mack (Henry Simmons) and Yo-Yo (Natalia Cordova-Buckley).

"I hope they can stay happy," Henstridge said of the science wonder twins. "It's Agents of SHIELD, nothing really stays good for long."

The younger relationships of SHIELD could take a few lessons from Hunter (Nick Blood) and Bobbi (Adrianne Palicki). Dubbed HuntingBird, the couple has had their fair share of complications, but, in the wake of Hydra's emergence, the pair managed to band together once more. Now that fools over at ABC have passed on Marvel's Most Wanted, perhaps Blood and Palicki will return to the mother ship.

Find out more when Agents of SHIELD returns to ABC this fall, now airing Tuesdays at 10 p.m. ET.
