It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, The helmed horrors then surround Vax and while the first one misses, the second once again strikes true with its weapon and deals heavy damage to the rogue. Keyleth sprints down the hall, sees Cassandra, and casts Healing Word on her.
DM: So one, two. He's going to attempt to grapple her. Go ahead and roll an athletics check with advantage because she's not expecting it.
Player: 16?
DM: Okay. Trinket grabs onto the scruff of her coat and begins pushing forward. They both get the rest of half of his movement because he's forcing her forward. That's as far as he can get.
Player: But I can keep running? I can run all the way up?
DM: What's your speed? Is it 30?
Player: 30.
DM: You get about there, right at the edge.
Player: So I can shoot an arrow?
DM: No, that's your movement and then your dash action to get there.
Player: Okay, cool.
DM: All right. Ripley is just going to stay put for the time being. She's held by a bear and being pushed along. She's just "Ugh."
