Scrounge for segues?

Hello everybody.

But we were not capable of asking, never mind answering. We were

young and poor, eating lunch at the office so we didn’t have to pay for it

ourselves. We scrounged for segues. Vadis had an aunt who’d hired an

exorcist once. Zach had a toaster oven that would turn itself on in the

middle of the night. That was pretty weird. Clive excused himself to make a

call.

I can't figure out the bold part. Would you please tell me what it means?

Thanks for the help ??
