"Agents Of S.H.I.E.L.D" fans should brace themselves for an exciting episode next season as there are flashbacks to S.H.I.E.L.D before it fell to its knees in the second "Captain America" movie and a charismatic Inhuman plays a crucial role in helping Skye realize her powers.

According to Comic Book, "Afterlife" will see Robert Gonzales make his move. Since he now has full control over the organization, there is no telling what he could do next. Coulson will do whatever it takes to protect the future of S.H.I.E.L.D, including gathering his team and protecting them. However, it may be harder than it seems due to Skye's powers and her running away with Gordon when Bobbi attempted to shoot her.

The episode's synopsis also teases that Skye's journey to control her powers takes a surprising turn when she meets an enigmatic Inhuman named Lincoln. TVLine reports that "The Tomorrow People" star Luke Mitchell will plays the role of Lincoln and he plays a pivotal role in assisting Skye to understand the true extent of her transformation.

Another TVLine report which features an interview with Henry Simmons reveals that this episode will showcase flashbacks of S.H.I.E.L.D before it fell to its knees in "Captain America: The Winter Soldier". It unveils the experience that bonded Mack, Bobbi, Isabelle Hartley and Robert Gonzales. This gives viewers a glimpse into their motivations to take down Coulson's S.H.I.E.L.D. Additionally, May's faith in Skye will be alleviated on Tuesday's episode and she will do whatever she can to save her.

Henry Simmons, who essays the role of Mack, explained the flashbacks, "The real S.H.I.E.L.D. emerged from everyone wanting to see the organization go in the right direction. Everyone is operating with good intentions." He also explained that Mack uses violence only when necessary and although he does respect Coulson significantly, he doesn't feel he is the right man for the job.

Watch episode 16 on Tuesday, April 7 at 9 p.m. ET on ABC.
