Forest Disturbance Arc

Demon Lord Attack
Tear managed to gain the info that Demon Lord Frey feared the return of Charybdis, and shared this info with Clayman. Clayman then offered Frey to eliminate the threat in exchange for a favor.

Footman and Tear incited Phobio to become the host of Charybdis in order to exact revenge against Demon Lord Milim Nava. As a result, Charybdis was eliminated by the combined effort of Rimuru and Milim, and Clayman earned the bargaining chip he desired.

The Octagram Soars Brightly Arc
While Clayman went to the Walpurgis Banquet, Laplace tried to infiltrate the Western Holy Church to try and find out the secret behind it. Footman and Tear helped to observe the war between Clayman's army and Milim's followers against the combined forces of Jura Tempest Federation and Beast Kingdom Eurazania.

Saint-Monster Confrontation Arc
They were seen mourning the death of Clayman.

Trivia

 * Ironically, it's the Clowns' schemes that made Rimuru and Jura Tempest Federation a superpower that poses the greatest threat to them, beginning with the Orc Lord's rampage. It's their schemes that forced Rimuru and Co. to seek allies and powerup themselves.
 * The Orc Lord incident led to Rimuru becoming a Demon Lord Seed and the formation of Jura Forest Alliance.
 * The Charybdis incident fostered the bond between Tempest and Carrion.
 * The scheme involving the Kingdom of Falmuth resulted in Rimuru awakening as a True Demon Lord.
