"Right..! In that case, let's just keep an eye out for anything that isn't a tree.."

That sounds like a plan, right? If something isn't a tree, then it's bound to either be a herb Nell can take along, or it's one of the dralites they can try to help out..

(Or it's a voidblob, but Madoka really doesn't want to think of that possibility. There's no way she could deal with something that dangerous.)

"Let's head in this direction, and please just tell me if you see anything while we walk, miss Nell..!"
