01 - Bring a large pot of salted water to a rolling boil. Cook linguine according to package directions until al dente. Reserve 1/2 cup pasta cooking water before draining thoroughly. Set aside.
02 - While pasta cooks, combine 2 tbsp butter and olive oil in a large skillet over medium-high heat until shimmering.
03 - Lightly season scallops with salt and pepper. Place in hot skillet and sear for 1-2 minutes per side until golden brown crust forms and just cooked through. Transfer to plate and reserve.
04 - Add lobster pieces to same skillet and cook 2-3 minutes until meat turns opaque and just cooked through. Remove from pan and set aside with scallops.
05 - Reduce heat to medium. Add remaining 3 tbsp butter, garlic, shallot, and red pepper flakes. Sauté 1-2 minutes until fragrant and garlic is pale golden, being careful not to brown.
06 - Pour in white wine and simmer 2-3 minutes until reduced by half, stirring occasionally to incorporate any browned bits from pan bottom.
07 - Add lemon juice and zest to skillet. Return seared scallops and lobster to pan. Gently toss to coat seafood in sauce, being careful not to break up delicate pieces.
08 - Add drained linguine to skillet, tossing with tongs to coat evenly. Add reserved pasta water as needed to achieve glossy, well-emulsified sauce. Fold in chopped parsley. Adjust seasoning with salt and pepper to taste.
09 - Divide among warmed plates. Garnish generously with additional fresh parsley and lemon wedges. Serve while hot.
