With Barry Allen's fateful accident now behind us, this week's episode of "Arrow" finds Oliver (Stephen Amell) dealing with a crazed bomber threatening the innocent citizens of Starling City, while Laurel (Katie Cassidy) digs deep into guest star Sebastian Blood's (Kevin Alejandro) past and finds something rather unexpected. Here are the biggest moments from "Blast Radius":

Barry's in Bad Shape

Felicity (Emily Bett Rickards) has gone to Central City to check on Barry Allen (Grant Gustin), who we soon discover was left in a coma after the events of the winter finale. Although Barry's accident has clearly transformed him into the Flash, it seems like it'll be a while before we actually see the Scarlet Speedster in action. Here's hoping we get a glimpse of the fastest man alive before this season is over!

Roy's Got Superpowers

After being injected with the coveted Mirakuru serum, Roy Harper (Colton Haynes) has developed a handful of superhuman abilities. So far, we've seen demonstrations of his super-strength and accelerated healing factor. What other enhancements could the serum have given him?

Oliver Looooooves Felicity

Upon Felicity's return, Oliver is clearly jealous of her spending so much time in Central City. While he may not be ready to admit it, Oliver clearly cares about his "partner" a little more than just as a friend. Olicity shippers, we could hear your screams from here.

Whatever Happened To Cyrus Gold?

Although seemingly killed in a previous episode, bad guy Cyrus Gold is brought up when Laurel goes looking for dirt on Sebastian Blood. Obviously, Cyrus still has the Mirakuru in his system despite being "dead." Could the "Arrow" version of DC Comics' baddie Solomon Grundy be coming back to life sooner, rather than later?

Slade's Out for Vengeance

Like Roy Harper, Slade Wilson (Manu Bennett) is one of the few lucky enough to survive the Mirakuru injection. Although Oliver attempts to console his friend (in a flashback) on the loss of Slade's love Shado, it's become quite clear that Slade has developed an unquenchable thirst for vengeance. Will Oliver telling Slade that he chose Sarah's life over Shado's will be the final turning point in their already uneasy friendship?

Sebastian Is the Devil!

After finding a woman named Maya Resik's medical records in Sebastian's office, Laurel pays the mayoral candidate's "aunt" a visit at the Langstrom Mental Institute... Only to discover that Blood killed his own father and locked his mother (who is Resik) away in an asylum. Clearly, Laurel was right about there being something off about Blood.

No Tam Reunion

Sadly, though Sean Maher guest-starred as the villainous Shrapnel, and Summer Glau has been guest-starring as the potentially villainous Isabel Rochev, there was no Simon Tam/River Tam reunion to satiate "Firefly" fans this episode. With Shrapnel still alive though, we've got our gorram fingers crossed.
