Passing a single class instance to another class

I finally got it all to compile without warnings and moved Arduino calls out of constructors:

main.ino:

#include "Puzzle.h"

Puzzle puzzle;

void loop(){
  puzzle.loop();
}

void setup(){
  puzzle.setup();
}

Box.cpp

#include "Box.h"
#include <Arduino.h>

Box::Box(Debug debug) : _debug(debug)
{
}

void Box::begin()
{
  _debug.begin();
  
  pinMode(28, INPUT_PULLUP);
}

Box.h

#ifndef BOX_H
#define BOX_H

#include "Debug.h"

class Box {
  private:
    Debug _debug;
    
  public:
    Box(Debug debug);
    void begin();
};

#endif

Debug.cpp

#include "Debug.h"
#include <Arduino.h>

Debug::Debug() : _state(false)
{
}

void Debug::begin()
{
  if (_state == false)
  {
    Serial.begin(9600);
    _state = true;
  }
}

void Debug::line(const char *messageChar)
{
  if (_state)
  {
    const char *p;
    p = messageChar;
    while (*p)
    {
      Serial.print(*p);
      p++;
    }
    newline();
  }
}
void Debug::line(int messageInt)
{
  if (_state)
  {
    Serial.print(messageInt);
    newline();
  }
}
void Debug::newline()
{
  if (_state)
  {
    Serial.println();
  }
}

Debug.h

#ifndef DEBUG_H
#define DEBUG_H

class Debug {
  private:
    bool _state;
  public:
    Debug();
    void begin();
    void line(const char *str);
    void line(int);
    void newline();
};

#endif

Puzzle.cpp

#include "Puzzle.h"
#include "Box.h"

Puzzle::Puzzle()
  : _box(_debug)
{
}

void Puzzle::setup()
{
  _box.begin();
  _debug.begin();
  _debug.line("Puzzle Setup");
}

void Puzzle::loop()
{
}

Puzzle.h

#ifndef PUZZLE_H
#define PUZZLE_H

#include "Debug.h"
#include "Box.h"

class Puzzle
{
  private:
    Debug _debug;
    Box _box;
    
  public:
    Puzzle();
    void setup();
    void loop();
};

#endif
