Get ready for a double shot of Private Practice!

Two episodes, "The Parent Trap" and "Blowups," will air back-to-back tomorrow evening on ABC. The titles are telling. In the former, Sam and Naomi must cope with their teenage daughter growing up too fast, while Addison has to contend with the Captain.

The latter? Well, you can take it literally.

"We all knew some sh!t was going down," Chris Lowell told E!, and he wasn't kidding. Dell’s home explodes, landing both his wife Heather and their daughter in the hospital.

“When it first happens, there’s total panic and hysteria,” Lowell teased.

That's nothing compared to when the cause of the blast is revealed, he says: “It rocks Dell’s world in a bad way. After this episode, he completely loses faith in a lot of things.”

Our guess? Heather's a meth dealer.
