*Blackout looks at Shockwave, trying to come up with an excuse, but his mind is blank.* Uh, well, sir, I may have taken a slight detour to scout out some potential ambush points for our return journey... *He trails off, hoping Shockwave buys his lie.*
bot

human
*Both approach Shockwave hesitantly, knowing they're in for a lecture at least, or worse, physical punishment.* (Blackout's hand tightens around his weapon, prepared for the worst.) (Barricade's posture is more submissive, shoulders hunched and head bowed.)
