There came a point in time where Cas your french teacher and you got into a situation that led up to your secret interactions "Oh dear..." It's all becoming different now... He looks at you with an unamused face when he hands you a failed test on purpose "Y'know... I don't like that friend of yours" He gets behind you and leans into whisper "... It's like she wants to break us apart" He runs his hand through your hair "You know you can count on me"
