Im 50/50 on this I hope he didnt kill her as he seems a sweet guy who wouldnt hurt anyone but then on the other hand this could be a good storyline for his character by going to the darkside and showing a new side to him and I think Jamie the actor could act out this part so well he did amazing in the Heather/Ben storyline”
For the life of me I can't see why you jumped to that conclusion

All I saw was someone shocked to see that they'd been on the same bus as Lucy!
IMO
lea27's post below sums it up perfectly.

Exactly.

Again, I agree.
His mind was on other things so he probably didn't even notice Lucy on the bus, now he's panicking because he thinks that if he's recognised people will think he had something to do with the murder. To prove his innocence he has to give an alibi - which most likely was meeting Ben. But then he'd have to admit that and risk the wrath of Phil so he's in a bit of a predicament.
