Ř1, D4: Oliver still hasn't figured out how to get back in Laurel's good graces, but a late night bonding session with Thea gives him the inspiration he needs. Looking into a suspicious murder case, Oliver realizes an innocent man, Peter Declan (guest star LANE EDWARDS), was framed by one of the targets on his list. As Arrow, he asks Laurel to help prove Declan's innocence. Meanwhile Walter asks one of his employees, Felicity Smoak (guest star EMILY RICKARDS), to look into a $2.6 million withdrawal that Moira made without his knowledge.
