The LGW based aircraft will fly to Scandinavian destinations too - here is the morning duty for two of them Mon-Fri:
LGW-OSL 06:10-09:15
OSL-LGW 09:45-11:05
LGW-ARN 06:30-09:50
ARN-LGW 10:20-11:55
I haven't had time to analyse it all, but with the return times to LGW I suspect a number of Norwegian flights have flown just before LGW based aircraft arrive and are ready to do their flights to the south. To me this says transfer. Many of the don't have direct flight during the week - only during the weekends. In other words more capacity without dedicating a single aircraft to each destination.
Edit:
I see only two DY 738 at LGW from the start in April to early September. Here is how the Saturdays for one of them looks like
LGW-DBV 06:25-10:05
DBV-LGW 10:45-12:20
LGW-SPU 13:20-16:45
SPU-LGW 17:25-18:50
LGW-MRS 19:20-22:10
MRS-LGW 22:40-23:30
