Should inside the rear 1/4 panel have drain holes to sill?

[ATK 139 1 Cars]

Got a leak where inside the rear 1/4 panel behind the trim card are filling up with water along the little channel.  Probably from my read window seals. 
 

question is - should this area have any drain holes or not (ie to drain into the sill underneath)? 
 

had new sills etc previously so wasn’t sure if I’m missing them as water is collecting there. 
 

am sorting new seams to sort the root cause by the way!!

Id need to check but I think there is an oval  slot just behind the outer skin that goes into the sill

Yes they do have one at least.

Here’s one I cut open recently.

New pattern sills I’ve used have this detail replicated fairly accurately.

Thanks Tom for the pic

 

i had my sills done about 10 years ago, this is a pic inside the car behind the rear trim below the quarter windows

 

i can’t see any visible drain holes here, am I correct that there should be a visible one along the channel? 
 

obviously the issue is to stop water getting there in the first place but I’m trying to establish if there should be a drain hole there just in case
