Meredith and Matthew were at the peak of the game, partly drunk and almost naked. Matthew is in his boxers while Meredith is in her undergarments and both her bra and panties are gone, it is at this critical moment when Matthew thinks. Well, this is it, throws the cards away, and leans closer to kiss her.
Meredith had her eyes closed almost as if she was ready for Matthew's kiss, her posture was enough to tell she was waiting for it, Matthew didn't delay any further. He planted a kiss on her lips and waited for Meredith to respond which she did.
While things were about to get intense, Meredith's phone starts to ring, she tries to ignore it but it didn't stop ringing 'damn this person, why don't you stop calling?' Meredith thought, suddenly Matthew pulled away from Meredith giving her a chance to pick up her phone.
