Sam was out at some clothing store that he didn't remember the name of when he got the phone call. "Hey, Dean, what's up?" He immediately asked when he answered, as a reflex.
"I-I need you to come home, Sammy. Now." Came the choked out reply from Dean, sounding distracted and worried.
"What's happened? Is something wrong?" Sam asked in a rush, focusing his full attention on his brother.
"I can't…. I can't explain it, but you need to get home now. I'm not hurt, just.. come." There was some muffling and it sounded like two people are arguing. Both voices were strangely familiar, but Sam could only point out Dean's.
"Dean, who else is there? De-" Sam was cut off as Dean hung up. Worried, Sam started searching through the store to find Kevin and Cas. "We need to go." Sam told them, trying to sound casual and failing miserably.
"Do we have to? I was just teaching Cas about mixing and matching clothing." Kevin complained, gesturing to the pile of clothes they had collected.
"Yes, we have to." Sam said fiercely, before turning and walking out of the store, knowing both of the shorter men would follow him.
The drive back to the bunker was short and tense, Kevin and Cas having noticed how on edge Sam was.
