Skills takes Mouth out on a jog and they end up at the old court (which was subject to be torn down for a new condo development) to rest up a moment. Skills teases Mouth about his weight gain, and when Mouth chuckles (in the close shot) you can clearly see parts of his facial prosthetic (which make him look fat) that were not blended in right, and a few cosmetic "puckers" (from sweat or the heat) on his upper cheek bone.
When Brooke is on the phone to Haley the call screen on Brooke's phone keeps rotating, meaning it is a picture on the phone not an actual phone call.
Dr. Alvarez and Quinn say that Clay's fugue state took him all the places you would take your child (by the pool, on the beach, on the playground.) This doesn't explain why he was buying drugs during his fugue state. Although Clay originally told Quinn it was from being shot and the prescription running out on his pain medication, he confessed to Dan that he didn't remember it, and was scared to tell Quinn the truth.
