ok so the quick deduction is Sherlock must’ve planned to overdose way before he got on that plane because he had to get enough drugs to do it. he planned it way before. he planned to die while reading John’s description of their first meeting. in which John calls him mad, arrogant and rude. and likeable. Sherlock planned to read that and close his eyes, doze off and just die. on a plane. alone. knowing John will never know the truth. goodbye
