I'm gonna say that after her bad injury Felicity's father forbids her to step foot from the house. Oliver can't see the person he has claimed in life and death- possessive beast indeed and it's got a smidge of feelings I'd say there under the surface. Oliver then has to do another climb the wall to her bedroom stunt and que a interesting scene where maybe even Oliver checks Felicity's injury to see for himself how bad/what was done to her. Correct? Just do a Oliver gif.
