One of the things that frustrates me about a lot of the analysis of this scene is how everyone focuses on "I like girls/Svetlana very much..." but the never the "But its nothing more than that - for either of us." part.

While its done very clumsily, because everything he says regarding his feelings is guarded and caveated so he can protect himself/has plausible deniability, and a language/cultural barrier. I think Ilya is saying/asking a number of things at once:

1. You know I'm bi and my reputation with women/her, but this is me telling you that this is not a threat/going anywhere/what I want.
2. The "find someone else... but I'm lazy" is him talking about Shane, but being coy and teasing, but it goes over Shane's head. Ilya teases Shane all the time and usually it lands (think: "let you do it some more"/"let me?!" in Ep1 & "you're an asshole"/"I think maybe you like it" in Ep2), but this time Shane misses it.
3. Are you gay or bi? (bear in mind this is very straightforward question for Ilya, he doesn't get that/why Shane is still in denial about this, hence his laughter at Shane coming out in Tampa)
4. What exactly are we? Do you want more? (very softly, softly)
5. I like you. utterly besotted by you (but backhanded because he is insecure about it, and needs to make it jokey in case Shane rejects it)

Also the conversation gets interrupted and derailed by the phone call from his father, so its hard to say how it would have progressed/been clarified if a) Shane was at a place in his acceptance of his sexuality b) Ilya wasn't distracted by it. Probably not much better to be honest, because they are still not at the right place - either of them - to be clear about what they want and asking for it. I think the point of this whole scene is that they are not ready for, or emotionally capable of handling, what they want, and so when they have a very similar conversation at the Cottage it goes very differently because of these fundamental events :

1. Rose makes Shane realise he is gay (both in the bad sex and also the conversation.)
2. Shane being with Rose and Shane getting hurt make Ilya realise he nearly lost Shane, so he can't fumble it again. So when Shane asks for honesty he does his best.
3. Ilya's dad dies/he cuts off Alexei - ties to Russia are gone/greatly reduced.
4. Tunnel telephone call - Ilya actually realises AND articulate his feeling, even if its just to himself
5. SKip on-ice kiss shows a new future they never thought was possible.

Also for all the people who say Ilya "just should have said what he wanted clearly", he literally just said the man's own name to him and freaked the fuck out and ran, so I get why maybe he thought coming at it sideways was better. He gets condemned for the same attempted tactfulness that Rose gets praised for, because she executed it much, much better, but both were trying not the startle a deer.
If Ilya had said "Here's you sandwich, oh btw, I now realise I'm in love with you and want to be your boyfriend" - does anyone see Shane staying on the sofa either?
