How would I stop a tween from another script?

I have an ability in my game that tweens the character forward and whenever that character hits a player, I want the tween to stop. I already have the script for detecting when the character is hit, but I don't know how I can stop the tween from the script that detects the player. I don't think it's possible to have both these scripts inside of one script.

Hiya, I don't want to be the sour apple, but could you please look up for answers?
