Tommy's (Colin Donnell) back! This doesn't bode well for Oliver (Stephen Amell), in the penultimate episode of Season 7 of Arrow, since his best friend is dead.

The CW has released photos from "Living Proof," and Team Arrow is looking bloody and bruised after Emiko (Sea Shimooka) lured them into a trap and set off explosives, bringing a building down on them. That left Oliver pinned and explains the "precarious position" the episode's description teases he's in.

Digg's stepdad isn't the only relative of OTA making trouble this season.

That likely also explains the return of Tommy. Oliver has hallucinated him before, in Season 2's "Three Ghosts."

Also in the episode, the SCPD has a warrant for Felicity (Emily Bett Rickards), the only team member not caught in the explosion (which is a good thing, since she's pregnant). Will she be able to figure out a way to help the others?

Click through the gallery above to see how Team Arrow is faring, both after the explosion and while dealing with the SCPD.
