Quarrelsome duo Martin Riggs and Roger Murtaugh's journey as mismatched police partners will continue in the upcoming episode of Lethal Weapon.

If anything, arguments and disagreements seem to be a frequent part of the chaotic life of ex-Navy Seal Riggs, who is yet to adjust to his new life as an LAPD officer. Solving crime and seeking justice tends to get even more difficult considering his rogue ways and the conflicts ensuing over his difference of opinion with his new partner Murtaugh.

Warning: Potential spoilers ahead, proceed at your own risk.

The same conflicting chemistry will once again take central spot in There Goes The Neighbour, when the detective duo decide to take on a case of burglaries that has occurred in Murtaugh's neighbourhood.

Although the pair finally starts investigating a series of crimes that have already led to a death, Riggs would have certain reservations about taking up the case. After a staple session of bickering, the by-the-book detective Murtaugh calls his difficult partner a "sand hobo", although a change of heart can be expected.

Meanwhile, Murtaugh's son Roger Jr will land in some trouble of his own as he reunites with an old friend with some history of illegal activities. In the midst of all the crime-solving and continuous conflicts, Riggs and Murtaugh are in for some comic setting this week as the duo enter counselling to help their ceaseless arguments.

Dr Maureen Cahill will play the mediator for the LAPD officers as they seek therapy to tackle their "erratic and impulsive" behaviour. When the police psychologist asks them if there is "something you could do to help nurture this relationship", the two will indulge in a comic rant about each other. While Riggs admires his "bald is beautiful" partner's round head, Murtaugh will admire the former's "not ridiculous" moustache.

To catch on with their epic rant and the action-packed episode, watch Lethal Weapon at 8pm EST on Wednesday on Fox.
