Eidolon sharing same space?

[DiceBagChick]

I am a newbie DM that just started a Pathfinder group. Most of us are newbies to Pathfinder except one guy.
Now, I've not heard/seen of Summoners until last night with an eilodon. Is the Eilodon a separate space or do they share the space? He's claiming they share the space as if they are 1 person with the shimmering aura of the eilodon around him.

He also is taking his evolution for flight, which, if i'm reading the rules correctly is not available to his eidolon until 5th level..

It depends,

If he is playing any type of Summoner beside a Synthesist, they are separate.

A Synthesist Summoner (archetype of the regular Summoner) wears his Eidolon like Power Armor.

You are correct, his Eidolon is ineligible for the flight evolution until 5th level.

Ah yes that's right, he did say he was a synthesis summoner. Thanks :)
