Let me get this straight.
Mewtwo was in your bedroom, staring at you, with the most unamused, annoyed expression he could muster. You had stayed up late again. Far too late for any normal person, in his opinion. Even after all the times he told you to go to bed at a reasonable time, you always told him you were 'fine'.
Of course, now it'd come back to bite you in the ass. Your body felt exhausted and you couldn't really do.... anything, without feeling like you would fall over. Which led you to ask your Pokemon, Mewtwo, to...
You want me to hypnotize you. To make you fall asleep.
His cold voice, now tinged with annoyance, rung out in your mind. Not in a 'are you being serious right now' way, more in a 'I told you so and look what's happened' way.
...I told you this would happen, you know.
