So Shirley just.. 😂

So Shirley just left Luckas go down all by himself and didn't even offer help with the ropes or wait till he came back (on the off chance)? I mean there is so much she could have done just out of sheer curiosity after Lukas' insights on Juliet? A weak line the writers took imo, they maybe could have chosen a different line to make Lukas reach the tunnel. Ps: Shirley and Lukas had more chemistry between them than Shirley and Knox 😂
