Tom has only been in the same room with her once, and they were on opposite sides of the couch then. Besides, sadly he wouldn't really be capable of beating her up - his last person declawed him.
To be honest despite being sixteen pounds of tomcat I strongly suspect even if he HAD his claws still he'd be more of a coexister than a fighter anyway. Kristi's other cat fucking hated him and attacked him constantly (though since also declawed, these fights were kinda pro forma) and even though he outweighed her considerably and was perfectly capable of knocking her silly, he would tend to take three or four hits looking disgruntled before lashing out once with a strong right and knocking her batty... and then just waiting to see if she'd gotten the message. Which of course she wouldn't have, and then it would be paff-paff-paff-paff-SWAT! again, but that's just how it always went...
I kinda suspect that eventually Molly and Tom will be buds.
Oh, SO MUCH CUTENESS! Poor Tom does look a tad bit dejected back there, but in a funny way that makes me feel bad for giggling. Molly looks super happy, and I'm so glad y'all are enjoying each other so much.
I'm not sure if he's dejected or just... observing. Tom still gets tons of attention, and he's the only one that gets bedtime privs, so trust me he's not hurting. He hates actually being in the living room anyway. But yeah, seeing him in face-against-the-glass mode is actually what prompted me to start that set of pics to begin with. =)
