Sometimes the wrong person triggers the trap. Fortunately, you have an answer for that.

Encounter   ✦     Arcane, Teleportation
Immediate Interrupt      Ranged 10

Trigger: A creature triggers a trap within range

Primary Target: The triggering creature

Secondary Target: A different creature within 10 squares of the primary target
