I was planning/considering/hoping that Tony and Chris would be separated at some point. Not only is it realistically likely to happen, but it would also do wonders for their character development.

If you want to, then you can have Tony having to run from the undead and meeting up with Remy and Ash's group. But it is totally up to you how/when you want to split them. Waiting until later is fine as well. ;)
