Sarah nodded, it was sensible advice. It would be foolish to rush to the hole to take a picture. She saw her Weedle going closer but he was still in the range of her pokeball to call him back she assumed so she let him be.

Weedle shrieked and wriggled but the grip was too firm. The ground got further away and his trainer got smaller and smaller. The words Rapier spoke barely got through. He had felt safer on the ground. Although slowly Weedle started to feel exhilarated soaring in the sky like this. If only he could fly all by himself.  

Sarah stepped a step forward when Rapier picked Weedle but when Regan said to keep distance she stepped back again, feeling the ground shake indeed. Regan had seen it too and didn't intervene so she decided to trust Rapier with this for now. 
"Saur, pay attention. This is a potentially dangerous situation and you need to be on guard, ready to strike," she said to her Bulbasaur. 
Saur nodded, looking at the ground, trying to pinpoint where the Onix was.

When the Onix emerged Sarah turned her face away and raised her arm to shield. Thankfully Regan could swat away one of the projectiles.
Sarah stared at the Onix for a bit until Saur nudged her. "Saur, if he strikes use vinewhip. If Onix sends more projectiles also use vine whip to try and keep us safe. She raised her pokedex and it's metallic voice rambled on about the Onix. Sarah snapped a picture and added a comment to it. She glanced behind them and was happy to see Weedle safe and sound on the ground again. "Are you ok?" Weedle nodded, "Use string shot to slow Onix down when he moves towards us. We will not engage if he doesn't."
