Alright, I'll bite.
If the first colonists hadn't been removed, many would have died, as was the case in most early attempts. The additional colonists show up, White leaves again for supplies, and the OTL poor weather and conflicts prevent him from returning until the same date as OTL. In the meantime, the not-much-larger than OTL population of Roanoke flees and joins the natives/dies as OTL, since the population change hasn't affected their circumstances.
Basically, all that happens is that more people die than OTL. The big problem with a Roanoke TL is that, while the disappearance may capture the imagination, weather and conflicts in England are what stopped White from mounting his return mission, rather than wherever the colonists may have gone.
